Answer

Answer key: Unit Rate worksheet

1. Better price: Option A is the better price
1. Divide Option A's price by its quantity to get the cost of one unit
  $\frac{$5.00}{26}$ $= 0.192308$
2. Do the same for Option B
  $\frac{$4.20}{12}$ $= 0.35$
3. Find the saving as a share of the higher cost
  $\frac{(0.35 - 0.192308)}{0.35} \times 100$ $= 45.054945%$
4. The lower cost per unit is the better price
  $Option A is the better price$
2. Rate (miles for each 1 in hours): 65.91
1. A unit rate tells you how much goes with exactly one. Divide the amount by the number of units to scale down to one
  $\frac{145}{2.2}$ $= 65.909091$
3. Rate (miles for each 1 in hours): 62.5
1. A unit rate tells you how much goes with exactly one. Divide the amount by the number of units to scale down to one
  $\frac{150}{2.4}$ $= 62.5$
4. Better price: Option B is the better price
1. Divide Option A's price by its quantity to get the cost of one unit
  $\frac{$4.20}{18}$ $= 0.233333$
2. Do the same for Option B
  $\frac{$2.90}{18}$ $= 0.161111$
3. Find the saving as a share of the higher cost
  $\frac{(0.233333 - 0.161111)}{0.233333} \times 100$ $= 30.952381%$
4. The lower cost per unit is the better price
  $Option B is the better price$
5. Better price: Option A is the better price
1. Divide Option A's price by its quantity to get the cost of one unit
  $\frac{$4.50}{34}$ $= 0.132353$
2. Do the same for Option B
  $\frac{$3.00}{18}$ $= 0.166667$
3. Find the saving as a share of the higher cost
  $\frac{(0.166667 - 0.132353)}{0.166667} \times 100$ $= 20.588235%$
4. The lower cost per unit is the better price
  $Option A is the better price$
6. Better price: Option B is the better price
1. Divide Option A's price by its quantity to get the cost of one unit
  $\frac{$5.40}{24}$ $= 0.225$
2. Do the same for Option B
  $\frac{$3.40}{16}$ $= 0.2125$
3. Find the saving as a share of the higher cost
  $\frac{(0.225 - 0.2125)}{0.225} \times 100$ $= 5.555556%$
4. The lower cost per unit is the better price
  $Option B is the better price$
7. Rate (miles for each 1 in hours): 60.42
1. A unit rate tells you how much goes with exactly one. Divide the amount by the number of units to scale down to one
  $\frac{145}{2.4}$ $= 60.416667$
8. Rate (miles for each 1 in hours): 41.67
1. A unit rate tells you how much goes with exactly one. Divide the amount by the number of units to scale down to one
  $\frac{100}{2.4}$ $= 41.666667$
9. Rate (miles for each 1 in hours): 85.71
1. A unit rate tells you how much goes with exactly one. Divide the amount by the number of units to scale down to one
  $\frac{180}{2.1}$ $= 85.714286$
10. Better price: Option B is the better price
1. Divide Option A's price by its quantity to get the cost of one unit
  $\frac{$5.60}{28}$ $= 0.2$
2. Do the same for Option B
  $\frac{$2.20}{18}$ $= 0.122222$
3. Find the saving as a share of the higher cost
  $\frac{(0.2 - 0.122222)}{0.2} \times 100$ $= 38.888889%$
4. The lower cost per unit is the better price
  $Option B is the better price$
