Lin's father is paying for a $20 dollar meal. he has a 15% coupon for the meal.

after the discount, a 7% sales tax is applied.

-what does lin's father pay for the meal?

a. 18.19%
b. 17.00%
c. 21.40%
d. 24.61%

Lin's father pay $18.19 for the meal

Step-by-step explanation:

Cost for meal = $20

He has a 15% coupon for the meal

Cost of meal after applying coupon =

Cost of meal after applying coupon =

After the discount, a 7% sales tax is applied.

Cost of meal after applying tax =

Hence lin's father pay $18.19 for the meal

stops on an even number.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
