Question

Ann made $143 for 11 hours of work.

Answer 1

Answer: 19

Explanation:
143/11=13
therefore Ann makes $13 a hour
243/13=approx 18.692
this can be rounded up to 19, as she likely makes money hourly

Therefore she must work for 19 hours to make $243

Answer 2

Answer:

22 hours

Step-by-step explanation:

So, 143 equals eleven hours. 143 plus 143 would equal 243. So, you have two 143s which means you should multiply the 11 hours by two. 11x2 equals 22.
