Explanation:

So, the shop spent $56 originally

Answer 2

The shop spent $56 originally.

Explanation:

Suppose, the shop spent
`x` dollars originally.

Given that, the total cost is 150% of what the shop spent originally. So, the total cost will be:
`(x* 150\%)= 1.50x` dollars.

The shop sells you a bicycle for $63 and a helmet for $21. So, the total cost
`= \$63+\$21= \$84`

Thus, the equation will be.........

`1.50x=84\\ \\ x=(84)/(1.50)=56`

So, the shop spent $56 originally.
