The regular price for a sweater is $48. the store is having buy one get one 1/2 off sale. if you buy 2 sweaters for that price what percent discount is that ?

25%

Step-by-step explanation:

Hi, if you buy 2 sweaters at full price (100%)

$48 x 2 = $96

"Buy one get one 1/2 off sale"´price

48 + (48/2) = 48 +24 = $72

So, the normal price for both sweaters (96) multiplied by a percentage is equal to the "buy one get one 1/2 off sale” price.

96 x =72

x =72/96 = 0.75  

Multiplying by 100 to obtain the percentage form

0.75 =75%

So, the sale price is %75 of the full price.

To obtain the percent discount.

100%-75% = 25%

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
