Answer: $120
Step-by-step explanation:
Assume the original price is x.
He sold the scooter for $130 and this was $50 less than 1.5 times what he paid for it.
Relevant formula is therefore:
1.5x - 50 = 130
1.5x = 130 + 50
x = 180/1.5
x = $120
Answer:
The equation is C, and the correct answer is 6 (D)
Step-by-step explanation:
We first look for the correct equation. If Matt charges 9 dollars per hour, and earned a total of 99, then we known that 9*the number of hours = 99. Moving on, we know that he babysat Friday night for 5 hours, but we don't know the number on Saturday. BUT we do know that 5+saturday hours = total number of hours. Putting this into a formula, we get 9(5+x (where x = #of hours worked on saturday) = 99(total number)
Our final equation is 9(5+x)=99.
Solving this by dividing both sides by 9, we get 5+x=11. Subtracting 5 from both sides gives us x = 6.
