Answer:
t-shirt: £5.00, hat: £2.00
Step-by-step explanation:
You can rewrite them into equations:
8t+h=42.
3t+h=17.
Then subtract the h from both equations using the elimination process.
8t-3t is 5t, and 42-17 is 25. The new equation is 5t=25, thus t=5. If we substitute the 5 into one of the other equations, we get h=2.
Answer:
T-shirt: £5
Hat: £2
Step-by-step explanation:
Use simultaneous equations elimination method for best results.
8t + h= 42
3t + h= 17
Subtract the two equations. h gets cancelled. 8t-3t= 5t. 42-17= 25.
5t= 25
t= 25÷5
t= £5
Substitute the value of t to give h.
8(5) + h=42
40+ h=42
h= 42-40
h= £2
