(a)
Paint needed for 1 gate = 1 u
Paint needed for 1 table = 3 u
Paint needed for 8 gates and 4 tables
= 8 x 1 u x 4 x 3 u
= 8 u + 12 u
= 20 u
58 of the paint = 20 u
18 of the paint = 20 u ÷ 5 = 4 u
Fraction of the remaining paint left
= 1 -
58=
38 38 of the paint = 3 x 4 u = 12 u
Remaining paint left = 12 u
Number of gates that Adam can paint with the remaining paint
= 12 u ÷ 1 u
= 12
(b)
Number of tables that Adam can paint with the remaining paint
= 12 u ÷ 3 u
= 4
Answer(s): (a) 12; (b) 4
