Question

Hi, help needed for this qn. Tq!

__________________

Collin paid  $181 for a shirt, a pair of pants and a tie. The pair of pants cost $15 lesser than the shirt. The shirt cost 2 times as much as the tie. How much did the pair of pants cost?

Answer

This  is a Part Whole question. 

Start from the Ratio.

   Shirt pant tie total 
  2u 2u – 15 1u 5u – 15 

5u – 15 = 181

5u = 181 + 15 = 196

1u = 196 ÷ 5 = 39.20

2u = 39.2 × 2 = 78.4

78.49 – 15 = $63.40
