Answer 1

3 hours

Explanation:

$12 = 2hours

Find how much Clare was paid for one hour

Total money earned ÷ number of hours = wage per hour

12 ÷ 2 = $6 per hour

set up equation

6x = 18

This equation says 6 dollars an hour × number of hours = $18

To solve for this equation, divide both sides by 6 (this isolates the variable)

6x ÷ 6 = 18 ÷ 6

1x = 3

x = 3
