Mari has a part time job. she earns $7 an hour. she makes at most $143.50 a week. what is the greatest number of hours that she worked

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

the five is the numerator

so first lets findout how much she spent so whats 32.00 - x = 9.20

32.00 - 22.75 =9.25. so she spent a total of $22.75 okay now we know the amount she spent. so now u got it from here.
