Question

Stefan sells Jin a bicycle for ​$138 and a helmet for ​$16. The total cost for Jin is 40 ​% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend​ originally?

Answer 1

Answer:

The original cost is

$385

Step-by-step explanation:

Step one:

given data'

cost of bicycle= $138

helmet = $16

Total cost = 138+16= $154

Step two:

let the original cost be x

we are told that 40% of x= 154

hence

40/100*x= 154

0.4x=154

divide both sides by 0.4

x= 154/0.4

x=$385
