Answer 1

Mr. Kelly bought
`x=3.5` pounds of chocolates

Explanation:

1. Lets name x the number of pounds of chocolates Mr. Kelly bought and write the equation to express the total cost of the trail mix:

(1.5pounds of peanuts)*$4.50 + (x pounds of chocolates)*$4.50 = $22.50

2. To find the number of pounds of chocolates Mr. Kelly bought you need to solve the equation for x:

`(1.5*4.50)+4.50x=22.50`

`6.75+4.50x=22.50`

`4.50x=22.50-6.75`

`4.50x=15.75`

`x=(15.75)/(4.50)`

`x=3.5` pounds of chocolates
