What is a unit rate?
Ksivusya [100]

Answer:

<em>A unit rate is something over a unit of something else. </em>

<u>Such as:</u>  (50 miles) / hour

If you have (150 miles) / 3 hours

This is not a unit rate, therefore you have to divide the top and bottom by 3 to get the unit rate

(150/3 miles) / (3/3 hours)

(50 miles) / hour

Hope this helps :)

Okay so x represents the amount of tickets sold. So first, you’d add the $40 + $70 which equals $110. So x = $110.

Now we have to solve for y. Same thing but with different numbers. $200 + $260 = $460.
The answer is (110,460)
x. y.
