Question

7 t - shirts and a hat cost 67.00

5 t - shirts and a hat costs 49.00
How much does a hat cost?
How much does a t - shirt cost?

Answer 1

Hat costs 4.00

T-Shirt costs 9.00

Explanation:

Let the t-shirt be t and the hat be h

7t+h=67

5t+h=49

Equating by eliminating the h and subtracting

the two equations,

2t=18

t=9.

If t =9 in 5t + h= 49 then

5×9+h=49

45+h=49

h=4
