Answer:
x - $42.50 = $124.99
Cost at local store = 167.49
Explanation:
The cost of skateboard on shopping online = $124.99.
Which is $42.50 less than the price at a local store.
Let the price of skateboard at a local store = x
As per the statement "the costs $124.99 which is $42.50 less than the price at a local store" the equation will be
x - $42.50 = $124.99
Now solve the equation and find the value of x
x - 42.50 = 124.99
x = 124.99 + 42.50
x = $167.49
The cost at the local store would be $167.49
