Cynthia buys 2 shirts, each costing $35, a pair of pants for $40 and a belt for $18. At the register the total she owes is $138.24. What is the rate of sales tax in her state?

The rate of sales tax in her state is 7.41%.

Step-by-step explanation:

First, you need to determine the cost of the items:

(35*2)+40+18=70+40+18=$128

Now, you can find the difference between the total Cynthia owes at the register and the cost of the items:

$138.24-$128=$10.24

Finally, you can use a rule of three to determine the rate of sales tax given that 138.24 represents 100%:

138.24 → 100%

10.24  →   x

x=(10.24*100)/138.24= 7.41%

According to this, the answer is that the rate of sales tax in her state is 7.41%.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
