Answer:
1. Original amount of bicycle and helmet = $56.
2. Amount of money earned by the friend = $28.
Step-by-step explanation:
We are told that my friend sells me a bicycle for $63 and a helmet for $21 . The total cost is 150% of what my friend spent originally.
1. Let x be the original price of bicycle and helmet spent by my friend.
Amount spent by me on both helmet and bicycle will be . We need to find x such that 150% of x equals 84. We can set this information in an equation as:
Therefore, my friend spent $56 on bicycle and helmet originally.
2. To find the amount of money earned by friend we will subtract amount spent by friend originally from amount spent by me on both items.
Therefore, my friend earned an amount of $28 by selling the bicycle and helmet to me.

Answer:
w = 6
Step-by-step explanation:
In this we know that 10/8 = w/4.8. 10/8 is equal to 1.25. Now we have 1.25 = w/4.8; multiply both sides by 4.8 to get rid of the fraction. We then end up with 6 = w; our final answer
