An instrument store has 20% clearance on every instrument. A guitar originally costs $120. You take it to the cashier and they charge a sales tax of 5%.
How much did you pay for the guitar?
Answer:
P = $100.80Steps:
Price after clearance:Pc = 120 - (120/100×20)
Pc = 120 - (1.2×20)
Pc = 120 - 24
Pc = 96
Price after sales tax:P = Pc + (Pc/100×5)
P = 96 + (96/100×5)
P = 96 + (0.96×5)
P = 96 + 4.8
P = $100.80
Answer:
I’m pretty sure the answer would be $100.80
Step-by-step explanation:
1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)
2. Subtract $120-$24= $96
3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8
3. Add $96+$4.80= $100.80
