Answer 1

First of all, calculate the quotient between 2.10 and 3/4 to determine the price per pound:

2.10/0.75 = 2.8 dollars per pound

Next, multiply 9.5 by the previous number todetermine the price of 9.5 pounds:

9.5 x 2.8 = 26.6 dollars

Hence, 9.5 pounds of grapes costs $26.6

pounds | price

0.75 2.10
