Find the unit rate for the given rate. Round to the nearest hundredth if necessary.
4. 30 cards for $5.20
5. 192 miles on 6 gallons of gasoline
32
5.20 / 30 = 0.17 each
Do the next problem the same way.
To find the unit rate, we need to divide the quantity by the corresponding cost.
For the first rate, 30 cards for $5.20, we divide the number of cards (30) by the cost ($5.20).
Unit Rate = Number of cards / Cost
= 30 / 5.20
ā 5.77 (rounded to the nearest hundredth)
Therefore, the unit rate for 30 cards for $5.20 is approximately 5.77 cards per dollar.
For the second rate, 192 miles on 6 gallons of gasoline, we divide the distance (192 miles) by the number of gallons (6).
Unit Rate = Distance / Number of gallons
= 192 / 6
= 32
Therefore, the unit rate for 192 miles on 6 gallons of gasoline is 32 miles per gallon.
