A shirt that cost $420 was discounted 20% for Bloomingdale's one day sale. When the sale was over, the shirt was marked up 20%. What is the cost of the shirt now?

$504

Step-by-step explanation:

Step one:

given data

A shirt that cost $420

we are told that the shirt was on a discount sale of 20%, so when the discount is over the price will return to $420, we are then told that the shirt was marked up 20%.

Step two:

Hence the new cost is

=20/100*420+ 420

=0.2*420+420

=84+420

=$504

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
