Question

You buy hamburgers at a fast food restaurant. A hamburger costs $0.49. You must have at most $3 to spend. Write an inequality for the number of hamburgers (b) you can buy

Answer 1

x ≤ 6.12

Explanation:

If the cost of 1 hamburger in a restaurant is $0.49, the amount of hamburger $3 can buy is expressed as shown .

$0.49 = 1

$3 ≤ x (since you have maximum of $3 to spend. It cant be more than that)

cross multiply to find the expression for x.

$0.49 * x ≤ $3 * 1

$0.49x ≤ $3

Divide both sides by $0.49

$0.49x/$0.49 ≤ $3/$0.49

x ≤ $3/$0.49

x ≤ 6.12

The number of hamburgers you can buy is represented by the inequality x ≤ 6.12
