Adamu spends 3/5 of his monthly allowance on food and 1/4 of the allowance on his learning materials. If the amount he spent on food and learning materials is #330 less than his allowance, how much is his monthly allowance?

15 answers

f = (3/5) a
e = (1/4) a

f + e = a - 330
so
(3/5)a + (1/4 a) = a - 330 multiply everything by 20
12 a + 5 a = 20 a - 6600
3 a = 6600
a = 2200
