I don't know but I guess there is an answer
75% of of the number 124 is 93
I think it's 9 but I could be wrong
3(x + 7) = 9(x - 1)
3(x) + 3(7) = 9(x) - 9(1)
3x + 21 = 9x - 9
<u>- 3x - 3x </u>
21 = 3x - 9
<u>+ 9 + 9</u>
<u>30</u> = <u>3x</u>
3 3
10 = x
His mom paid 30 and he paid 10 I did 40÷4 the got 10 then times by how many 25% each had
