2. Lebron bought a new pair of basketball shoes that were on sale for 25% off. If he paid a total of $150, what was the original price of the shoes?
A. $37.50
B. $112.50
C. $200.00
D. $187.50
1. The total cost before tax is $1.25 + $7.25 = $8.50. To calculate the sales tax, we need to multiply the total cost by 10%, which is 0.10 in decimal form. So, the sales tax is $8.50 x 0.10 = $0.85. Therefore, the total bill including sales tax is $8.50 + $0.85 = $9.35.
Answer: D. $9.35.
2. If Lebron paid $150 for the shoes with a 25% discount, then he only paid 75% of the original price. Let x be the original price of the shoes, then we can write the equation:
0.75x = $150
Solving for x, we can divide both sides by 0.75:
x = $150 รท 0.75 = $200
Therefore, the original price of the shoes was $200.
Answer: C. $200.00.
