Olivia sells t-shirts on a website. She earns $3 from each t-shirt she sells. Every month, Olivia must pay $20 to the website, no matter how many t-shirts she sells. Write an expression representing how much money Olivia earns after selling x amount of t-shirts in the month of November.

Ahaha, ain't it ironic that my gf is also named Olivia? Pfft! She's super smart so I know she'll go far in life. She's super cute, hot, and smart too. Has every good quality.. <3

Anyway, back on point.

3x-20=y.

20 is the independent variable, because it doesn't depend on anything, which  would make it the b variable in mx+b. Since there's something being subtracted, 20 is negative. M is 3 as it is dependent. It's positive as there's nothing being subtracted.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
