9. 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.

a. how much did the shop spend originally?

b. how much profit did the bike shop earn by selling the bicycle and helmet to you?

Initial cost = $56

Profit = $28

Step-by-step explanation:

A bicycle costs $63

A helmet cost $21

The total cost is 150% of what the sho spent originally for these tiems:

The total cost is C = $63 + $21 = $84

and we know that this cost is the 150% of the initial cost, K:

C = (150%/100%)*K = 1.5*K

So the initial cost is:

K = C/1.5 = $84/1.5 = $56

The profit will be the difference between the two costs:

P = C - K = $84 - $56 = $28

So the shop earns $28 by selling the bicycle and helmet
