Answer: Joseph earns $271.2 in one week.
Step-by-step explanation:
Let x be the amount of money that Joseph makes in one week.
Therefore, the fraction of money Joseph spends on his jacket is x times the weekly earning.
5/24 = 56.50/x
Cross-multiplying (draw the equation above on paper if it seems confusing)
5x=24 x 56.50
24 x 56.50= 1356
5x=1356
We divide 5 and 1356 by 5 to get x by itself.
x= 271.2
