Your friend sells you a bicycle for $45 and a helmet for $13.the total cost is 110% of what your friend spent originally. how much did your friend spend originally? how much money did your friend earn by selling the bicycle and helmet to you?

total price to be sold is  45+13=58 but we are told that this price is 110% of the origoinal,  so we ask ourselves if 58 is 110% WHAT IS VALUE OF 100%

Step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
