Question

7 t-shirts and a hat costs £67.00 5 t-shirts and a hat costs £49.00. How much does a t-shirt cost? How much does a hat cost?

Answer 1

Answer:

9 and 4

Step-by-step explanation:

Let the cost of each t-shirt be ' x '

Let the cost of each hat be ' y '

Then the equation will be

7x+y = 67 ........ eq 1

5x+y = 49 ..........eq 2

Subtract that is eq1 - eq2

7x +y = 67

-5x-y = - 49

2x=18

.°. x = 18/2 = 9

Substitute x = 9 in eq 1

7 ( 9) + y =67

63 + y = 67

y = 67 - 63 = 4

Cost of each t-shirt = 9

Cost of a hat = 4
