N=8

7.50 x 8 = 60

60 + 15 = 75

Work backwards it’s easier!

Common sense tells you that if 15 plus something equals 75 then that something has to be 60

You then see that 7.50 has to be multiplied by something to get you 60 so simply guess and check!

75 - 15 = 60

60 / 7.5 = 8

n = 8

Hope this helped☺☺
