Question

The cost of a car is supposed to be no more than 80% of the value for the next year's

model. If a car costs $14,000, what is the cost of the next year's model?

Answer 1

x ≥ 17,500

Explanation:

To solve this problem, we will follow the steps below:

let x be the cost of the next year's model

Writing the question in a mathematical format yield

$14,000 ≤ 80% of x

This implies ;

80% of x ≥$14,000

80% × x ≥$14,000

`(80X)/(100)` ≥ $14,000

multiply both-side of the inequality by 100

`(80X)/(100)` × 100 ≥ $14,000 × 100

at the left hand-side of the inequality 100 will cancel-out 100 leaving us with just 80x

80x ≥ $1,400,000

Divide both-side of the equation by 80

80x /80 ≥ $1,400,000/80

x ≥ 17,500
