Question

elena bought 2.2 pounds of each type of fruit shown on the sign. what was the total cost of the fruit she bought? answer 4–6.

1. write an equation to model the problem. let c be the total cost of the fruit elena bought. choose the correct answer below

a. $c = 2.2 + (\\$1.30 \times \\$1.35 \times \\$0.85)$
b. $c = \\$1.30 + \\$1.35 + \\$0.85$
c. $c = (2.2 \times \\$1.30) + (2.2 \times \\$1.35)$
d. $c = (2.2 \times \\$1.30) + (2.2 \times \\$1.35) + (2.2 \times \\$0.85)$

1. what is the solution to the problem?

the total cost of the fruit elena bought is $\square$.
(type a whole number or a decimal.)

pears $\\$1.30$/lb
grapes $\\$1.35$/lb
apples $\\$0.85$/lb

Explanation:

Step1: Identify the cost formula

The cost for each fruit is (pounds bought) × (price per pound). Elena bought 2.2 pounds of each of three fruits: pears, grapes, apples. So we calculate the cost for each and sum them.

Step2: Use the equation from question 5 (option D)

The equation is \( c=(2.2\times\$1.30)+(2.2\times\$1.35)+(2.2\times\$0.85) \). Factor out 2.2: \( c = 2.2\times(\$1.30 + \$1.35 + \$0.85) \).

Step3: Calculate the sum inside the parentheses

\( \$1.30 + \$1.35 + \$0.85 = \$3.50 \).

Step4: Multiply by 2.2

\( c = 2.2\times\$3.50 = \$7.70 \).

Answer:

7.70
