An 8-pound bag of tomatoes costs $5.60. at the same rate, what would be the cost of 11 pounds of tomatoes?
a. $8.50
b. $7.00
c. $7.70
d. $6.50

Here is the solution to the given problem above.
Given that for an 8 pound bag of tomatoes costs $5.60, we would want to know how much will it be for 11 pounds. First, we should know how much does it cost per pound. So 5.60 divided by 8 is 0.7. So per pound of tomatoes costs $0.7. Now to know how much for 11 pounds, we multiply 0.7 by 11 and we get $7.70. The correct answer therefore would be option C. $7.70. Hope this answer helps.
