A computer store buys a computer system at a cost of $463.80. The selling price was first at $ 773, but then the store advertised a 20 % markdown on the system. Answer parts a and b.
a. Find the current sale price.

Sale prizes:

Part A: 463.80 - 92.76 = $371.04

Part B: 773 - 154.6 = $618.4

Step-by-step explanation:

Formulas used in the calculation:

discount amount/original price = discount%/100%

Sale price = original $ - discount$ = final answer

Part A:

discount amount = x

original price = $463.80

discount amount = 20%

x/463.80 = 20/100

x · 100 = 20 · 463.80

100x = 9,276

100x/100 = 9,276/100

x = $92.76

Part B:

discount amount = x

original price = $773.00

discount amount = 20%

x/773 = 20/100

x · 100 = 20 · 773

100x = 15,460

100x/100 = 15,460/100

x = $154.6

Sale prizes:

Part A: 463.80 - 92.76 = $371.04

Part B: 773 - 154.6 = $618.4

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

5/20 so 25%
