Question 150351: Maximum height. If a soccer ball is kicked straight up from the ground with an initial velocity of 32 feet per second, then its height above the earth in feet is given by s(t) = -16t² + 32t where t is time in seconds. Graph this parabola for 0≤ t ≤ 2.
What is the maximum height reached by the ball?

Question 150714: Hello E-Tutors:)

Could someone lead me in the right direction with this college
system of equations and inequality problem? The text book shows
how to solve something similiar but it only displays an equation
with two variables. Whereas this problem contains three variables.
That throws me for a loop.

Problem: The students from algebra class go for coffee together
every day. On Monday, Jordan paid $5.45 for three cartons of milk,
four cups of coffee, and seven doughnuts. On Tuesday, Ryan paid $5.30
for four milks, two coffees, and eight doughnuts. On Wednesday, Zack
paid $5.15 for two milks, five coffees, and six doughnuts.

1. Set up a system of equations to model this scenario.

I think this is right, but have no idea how to solve three layers,
with 3 different variables.
m=milk
c=coffee
d=doughnut

3m + 4c + 7d = 5.45
4m + 2c + 8d = 5.30
2m + 5c + 6d = 5.15

2. Determine the cost of one carton milk, one coffee, and one doughnut
by solving they system.

3. If on Thursday, Taylor had to pay for five milks, two coffees, and nine
doughnuts how much did he spend?

Think, I can get this one if I learn how to solve the second question.

Thank you in advance for sharing your valuable skills with us,
mishap mathematicians. :0)

Grateful,
Jai
