Given is that Holly works as a consultant who earns a weekly salary, plus an amount every hour she works. If her total earnings are represented by (y) for (x) total hours worked in the table below -
Hours: 5 6 7 8
Amount : 450 480 510 540
We can write the unit rate as -
r = (480 - 450)/(6 - 5)
r = 30/1
r = 30
Therefore, she earns a total of $30 per extra hour of her work.

Pine Hill Middle School has 300 students. In
Zoey's class, two out of five students belong to
a club. Use this ratio to predict how many
students in the school belong to a club.
There are 120 students in the school Pine Hill Middle School who belong to a club.
What is a ratio?A ratio describes a comparison between two or more quantities in simplest form.
Given that Pine Hill Middle School has 300 students.
Also given two out of five students belong to a club.
∴ We can conclude that (2/5)th of the total students belong to the club which is numerically,
= (2/5)×300.
= 120 students.
We can also solve this by ratios if in a total of 5 students 2 students belong to a club that means 3 students doesn't belong to the club and their ratio is 2:3.
∴ The no. of students belonging to the club is 2/(2+3)×300.
= (2/5)×300.
= 120 students belong to the club.
