Sandy programmed a website’s checkout process with an equation to calculate the amount customers will be charged when they download songs. the website offers a discount. if one song is bought at the full price of $1.29, then each additional song is $.99. state an equation that represents the cost, s , when c songs are downloaded.

9.95 + 0.30s=c

replaces s with 35

9.95 +0.30(35) =c

9.95 + 10.50 = 20.45

it will cost $20.45

Step-by-step explanation:

C=1.29+0.99(S-1)

They were asking for an equation

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
