A chef is making 20 pounds of fruit salad to sell in his shop. The chef will use only grapes and
blueberries in the fruit salad. Let x and y be defined as follows:
x = the number of pounds of grapes the chef will use
· y = the number of pounds of blueberries the chef will use
a. Write an equation in terms of x and y that can be used to represent the total number of pounds
of fruit salad the chef will make.
Grapes cost $2.50 per pound, and blueberries cost $4.00 per pound. The chef spent a total of $59.00
for grapes and blueberries for the fruit salad.
b. Write an equation in terms of x and y that can be used to represent the total cost, in dollars, of
the fruit salad.
c. Use your answers from parts (a) and (b) to determine the number of pounds of grapes and the
number of pounds of blueberries the chef will use to make the fruit salad. Show or explain how
you got your answer.
