Question

Eva is picking fruit at a farm. The fees are $5 for entry to the farm, $2.50 per pound of blueberries, and $2 per pound of apples she picks to take home. Let b be the number of pounds of blueberries and a be the number of pounds of apples Eva picked. Which of the following expressions could represent how much Eva pays?
I'm just curious

Answer 1

Answer:

The required expression is: $y = 5 + 2.50b + 2a$

Step-by-step explanation:

Given

$Entry = \ 5$

$Blueberry = \ 2.50$

$Apple = \ 2$

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

$y = Entry\ Fee + Blueberry = Apple$

$y = 5 + 2.50 * b + 2 * a$

$y = 5 + 2.50b + 2a$

Hence, the required expression is: $y = 5 + 2.50b + 2a$
