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

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
