Question

Jesse bought 5.2 pounds of grapes for $7.75. Using the unit rate, how much would 3 pounds of grapes cost?

Answer 1

The cost of `3` pounds of grapes `=color(green)($4.47`

Explanation:

Cost of `5.2` pounds of grapes `= $ 7.75`

Cost of `1` pound `= 7.75/5.2 = color(blue)( $1.49` (rounding off to the nearest `100`)

So, now we can calculate the cost of `3` pounds of grapes:
`= color(blue)(1.49) xx 3 = $4.47`
