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

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

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`
