t^3=64/27
Hint: we multiply fractions straight across!
t=4/3
200
Is this a function?
Yes because each input has one output

In one city, the cost for a gym membership is given by the equation y=32.50x+65 , where y is the total cost, in dollars, for a membership for a certain number of months, x.
What is the cost, in dollars, of a gym membership for 6 months? Show your work!
y=32.50 (6)+65
y=195+65
y=260

Lydia and Bryce are traveling on their bikes at a constant speed. Lydia travels 3 miles in 18 minutes. Bryce's speed is defined by the equations y=5x, where y represents the amount of minutes that it takes Bryce to ride x miles.
Find Bryce's speed in miles per minute.
WARNING: The equation for Bryce is written with bad form! Normally time is the independent variable, x, but they are trying to trip you up and made it the dependent variable, y!
1/5 or .2 miles per minute
