You can put this solution on YOUR website!
You work 6 hours on a saturday. So for that single day, you earn 5.50*6 = 33 dollars (at $5.50 an hour).

Let x = number of saturdays that you work

if you work for x saturdays, and you earn $33 each time, then you earn a total of 33x dollars (33x means 33 times x)

We want this equal to $350, so

33x = 350

divide both sides by 33 to get

33x/33 = 350/33

x = 350/33

x = 10.606 (this is approximate)

Then we round up to go from 10.606 to 11

So you must work 11 saturdays to have at least $350
