Question

Kate is allowed to work no more than 20 hours a week. She has already worked 13 hours this week. At most, how many more hours CAN she work? Write and inequality and solve.

Answer 1

13 + x = / < 20
-13 --------- -13

x = / < 7

Kate can work seven hours at the most. Hope this helps!

Answer 2

h ≤ 7

h stands for hours. We use the less than or equal to symbol, since she can work 20 hours, but nothing above that, and she can also work less than 7 hours.
