Destiny needs a new coat for the winter and she found one at old navy for $48.88.the sales tax is 8% . how much will she pay for the sales tax?

she will pay $3.91 for sales tax

Step-by-step explanation:

First you take the amount 48.88

next you will multiply 48.88 by .08

(8% in decimal form is .08)

then it comes out as 3.9104

Since you cant have a fourth of a penny you round to the nearest hundredth

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
