Question

A skateboard was reduced in price from $50 to $43.

What was the percent decrease?

Answer 1

50-43 = 7

7/50×100=14℅ DECREASE

Answer 2

Answer:

It was reduced by 14%.

Step-by-step explanation:

1. Write an equation. Let s be the price of the skateboard, r be the rate that is was reduced, and p be the sale price. s-sr=p
2. Substitute values. We know that s is 50 and that p is 43. 50-50r=43
3. Begin isolating the variable. Subtract 50 from both sides to cancel out the 50 on the left side. -50r=-7
4. Finish isolating the variable. Divide both sides by -50 to get the r alone. r=-7/-50
5. Simplify. r=0.14 This means that the it was reduced by 14%.
6. Check your answer. Replace the r in the original equation with 0.14 50-50(0.14)=43 becomes 50-7=43, which is further simplified to 43=43

The answer is correct!
