Aconcert ticket that originally cost $46.50 is on sale for $38.75. what is the percent of decrease, rounded to nearest tenth?

To start with let's find the difference in price

46.5-38.75 = 7.75

now we can make a proportion

7.75       x
=
46.5       100

then cross multiply and divide

100 times 7.75 = 775 divided by 46.5 16.7

the percent of decrease is 16.7

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
