Answer:
Adults that clean in March = 18
Adults that clean in April = 48
Adults that clean in May = 4
Step-by-step explanation:
Adults that clean in the months of March, April and May = 70
Let a represent March, b represent April and c represent May.
Therefore, a + b + c = 70 (i)
From the question, the number of adults that clean in April is 14 more than number of the adults cleaning in months of March and May combined.
b - ( a + c) = 14 (ii)
also, the total number who clean in April and May is 2 more than three times the number who clean in March.
b + c - 3a = 2 (iii)
From (i), a + c = 70 - b (iv)
Substituting (iv) into (ii), b - ( 70 - b) = 14
b -70 + b = 14
2b = 84, b =48
Therefore a + c = 70 - 48
a + c = 22; c = 22 - a (v)
Substituting (v) and b = 48 into (iii)
48 + 22 - a -3a = 2
4a = 72, a = 18
Therefore, c = 22 - 18
c = 4
