Question #40195

Answer 1

$1.40

Explanation:

`("cost per pound of grapes")("pounds of grapes")=("total cost of grapes")`

Following this word equation, we can see that the cost per pound of grapes is what we are trying to find, the pounds of grapes is `3 1/4=3.25`, and the total cost of the grapes is $4.55.

We can plug in these values into the equation and solve:
Let `u` be the unit cost of the grapes or cost per pound of grapes
`u(3.25)=4.55`
By dividing both sides by 3.25, we get:
`u=4.55/3.25=1.4`

Therefore, the unit cost per pound of grapes is $1.40
