Question

A bike shop sells you a bicycle for $63 AND A HELMET for $21. The total cost is 150% of what the shop spent originally. How much did the shop spend originally

Answer 1

Answer:

The shop spent $56 originally.

Step-by-step 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:  $(x\times 150\%)= 1.50x$ 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.........

$1.50x=84\\ \\ x=\frac{84}{1.50}=56$

So, the shop spent $56 originally.
