Question

5t-shirts and a hat costs £83. 00,2 t-shirts and a hat costs £38. 0. A)how much does a t-shirt cost?

Answer 1

t- shirt costs £15

Explanation:

let cost of t- shirt be t and cost of hat be h

construct a pair of simultaneous equations from the given information, that is

5t + h = 83 → (1)

2t + h = 38 → (2)

subtract (2) from (1) term by term to eliminate h

(5t - 2t) + (h - h) = 83 - 38

3t + 0 = 45

3t = 45 ( divide both sides by 3 )

t = 15

the cost of a t- shirt is £15
