there were half as many yellow shirts as blue shirts in a box and 15 more green shirts than blue shirts. (more in description)

Question

there were 27 yellow shirts. how many shirts were left in the box when 4/5 of the shirts were taken out?

Answer 1

Y = B/2 = 27 yellow shirts

B =2Y = 2(27) 54 blue shirts

G =54+15 = 69 green shirts

total shirts = 27+54 + 69 = 150

4/5 of 150 = 120

150-120 = 30 shirts left after 4/5 are removed
