940 pounds

Explanation:

Answer 2

The weight of last year's model was 940 pounds

Explanation:

Remember that

`100\%-15\%=85\%=85/100=0.85`

Let

x ----> last year's model weigh in pounds

we know that

Last year's model weight multiplied by 0.85 must be equal to the weight of the newest year's model

so

The linear equation that represent this situation is

`0.85x=799`

solve for x

`x=940\ lb`
