Question

The cost of 2 baseball bats, one aluminum, one wooden, is $300. If the aluminum bat costs $40 more than the wooden bat, how much does the aluminum bat cost?

Answer 1

a + w = 300
a = w + 40

(w + 40) + w = 300
2w + 40 = 300
2w = 300 - 40
2w = 260
w = 260/2
w = 130 <=== cost of wooden bat

a = w + 40
a = 130 + 40
a = 170 <=== cost of aluminum bat

Answer 2

total cost= bat + bat
300= W + A

W= wooden bat
A= Aluminum bat= W+40

300= W + A
300= W+(W+40)
300= 2W+40
260= 2W
W= $130

A= W+40= 130+ 40= $170


Answer:
Aluminium bat= $170
Wooden bat = $130
