Aconsumer charges a $2,530.16 purchase on their credit card. the card has a daily interest rate of 0.042%. if the consumer pays off the balance at the end of 30 days, how much more in interest will they pay for the purchase?
a. $0.32
b. $3.19
c. $31.88
d. $318.78

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

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
