Question

Sandy programmed a website's checkout process with an equation to calculate the amount customers will be charged when they download so. The website offers a discount. If one song is brought at the full price of $1.29, then each additional song is 99 cent State an equation that represents the cost, f(×) and when X songs are downloaded ​

Answer 1

f(x) = 0.99x + 0.3

Explanation:

f(x) = 1.29 + 0.99(x - 1)

Distribute

f(x) = 1.29 + 0.99x - 0.99

Combine like terms

f(x) = 0.99x + 0.3
