Q(t)=45-t gallons per minute ; where t is in minutes
Number of gallons in tank after 30 minutes ;
Q(t)=45-t
Q(30) = 45 - 30
Q(30) = 15
Hence, Number of gallons in tank after 30 minutes is 15 gallons

The local hamburger shop sold 115 hamburgers and 345 cheeseburgers on Friday.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent the number of hamburger sold and y represent the number of cheeseburgers sold, hence:
x + y = 460 (1)

y = 3x (2)
From both equations:
x = 115, y = 345
The local hamburger shop sold 115 hamburgers and 345 cheeseburgers on Friday.
