Question

The total cost of blueberries at the farmers market varies directly with the weight. Victor paid $2.73 for 2.6 pounds of blueberries.

Complete the multiplication equation to find how much any weight of blueberries would cost. Lett represent the total cost, and let w represent the weight of the blueberries.

Answer 1

`t = wR_p [R_p = 1.05]`

Explanation:

For the case of victor: , let total cost be
`t_v = 2.73` and total weight be
`w_v = 2.6`.

So the price rate per 1 pound of blueberries should be,

`R_P = (t_v)/(w_v)\\= (2.73)/(2.6)\\= 1.05\\`

For general case: 1 pound costs
`R_P` so
`w` pound costs
`wR_p` pounds. So the equation should be,

`t = wR_p [R_p = 1.05]`
