I do not see any other zero other than that in the $50. I will still try to help. The zero in 50 denotes that 50 is a multiple of ten. I hope this helped.
Kenny can buy 15 t shirts and 3 sweatshirts.
Step-by-step explanation:
Given,
Number of members = 18
Cost of each t shirt = $9
Cost of each sweatshirt = $15
Money = $180
Let,
x be the number of t shirts
y be the number of sweatshirts
According to given statement;
x+y=18 Eqn 1
9x+15y=180 Eqn 2
Multiplying Eqn 1 by 9
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 6
Putting y=3 in Eqn 1
Kenny can buy 15 t shirts and 3 sweatshirts.

Step-by-step explanation:
First step is to identify what the problem is asking for and what is given.
9 laps in 28 minutes
Searching for number of laps in 1 hour and 15 min.
1 hour + 15 min. = 75 minutes convert to minutes
9 laps / 28 minutes = x laps / 75 minutes create an equation
9/28 = x/75
9*75 = 28x cross multiply
675 = 28x
x = 675/28 = 24.12 simplify
Melanie can run 24 complete laps in 1 hour and 15 minutes.
