Question 1160513

Erica gets $0.60 an hour for ordinary time and $0.90 an hour for overtime if she gets $32.40 for 50 hours a week how many hours overtime
<pre>Let amount of overtime hours be T
Then amount of regular-time hours = 50 - T
We then get: .9T + .6(50 - T) = 32.4
.9T + 30 - .6T = 32.4
.3T = 2.4
Amount of overtime hours, or {{{highlight_green(matrix(1,5, T, "=", 2.4/.3, "=", 8))}}}
