Steve joined a gym with a first month deposit of $50 and a $20 monthly fee every month after that. How much will Steve spend for an entire year of membership? Write the explicit form of the equation and find the correct answer.
f(m) = 20 + (m-1)(50)
f(m) = 50 +20(m)
f(m) = 50+(m-1)(20)

The Miller Football Team holds a car wash to raise money. The team spends $12.50 on supplies and charges $5.00 per carwash. Write an equation to represent the amount of profit.
y = 12.50x + 5.00
y= 5.00x + 12.50
y=5.00x - 12.50
y= 12.50x - 5.00
Jane has a giftcard for $25 for CoffeeBux. She buys a $3.00 drink everyday with her giftcard. Write an equation to represent the situation.
y= - 3.00x + 25
y= 25x + 3.00
y= -3.00x - 25
Y=3.00x +25
A balloon is released from the top of a 50-foot building. The balloon rises at a rate of 2 feet per second. What equation represents the height of the balloon after x seconds?
