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.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times
