Question

7. Saturday night, Larry is attending the concert of his favorite rock band. Tickets were $250 plus 6% tax. Parking is $20 for the evening. While there, Larry purchases a T-shirt for $35 plus 7% tax and a meal with a beverage for $25. How much did he spend altogether to attend the concert?​

Answer 1

$347.45

Explanation:

total = tickets + parking + t shirt + meal

tickets = 250 + 6% tax

6% tax is of 250, so this is equal to

250 + 6% of 250

6% = 0.06 because we divide by 100 to convert to a decimal from a percentage

thus, tickets = 250 + 0.06 of 250 = 250 * 1 + 0.06 * 250 + 1.06 * 250 = 265

parking = 20

use a similar strategy from the tickets and apply that to the t shirt

t shirt = 35 + 7 % tax = 35 + 0.07 * 35 = 1.07 * 35 = 37.45

meal = 25

total = 265 + 20 + 37.45 + 25 = $347.45
