All the items on the sale rack were 75 percent off their original price.
tresset_1 [31]

Answer:

112 $ is the original price

Step-by-step explanation:

x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112

you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale

Use the formula, I = PRT, to find the time if | = $387.50, P = $1,550, and R = 12.5%
stiks02 [169]

Answer:

T = 2

Step-by-step explanation:

Take the given formulaer

I = PRT

And plug in the variables you know (I, P, R)

387.50 = 1,550(.125)T

(12.5% becomes .125 after you divide it by 100, because precents are really just fractions out of 100)

387.50 = 193.75T

T = 2
