This is what i would do i would do this is every student has 40 then 1 student has 40 then he gets a movie ticket so 40 - 5 = 35 then he buys candy for 7.50 so 35 - 7.50 = 27.5 then buys a 2 dollar trolley ride so 27.5 - 2 = 25.5 so every student was left with 25 dollars and 5 cents
Answer:
4n and 5p
Step-by-step explanation:
Because if it the cost of each your mulitplying and because you wanting to just define the variable p for pen and n for notebook all a variable is a letter than let you know what something is for using in math later
You could use many methods to find the answer to this problem, but I am going to use the most efficient one I know.
18f+15(4f)=156
F is for fins. We should now solve the equation.
18f+60f=156
78f=156
156÷78=2
So fins cost 2 dollars. Now, we know snorkels cost four times the amount of fins. Four times 2 is eight. So the snorkels cost $8 to rent. Let's check our math.
15(8) + 18(2)
120+36=156
So it cost $8 to rent a snorkel.

Kym teaches sixth grade students in an urban school where most of the families in the community live below the poverty line. Each year the majority of the students in her school fail the statewide tests. Kym follows school district teaching guides and typically uses direct instruction in her Language Arts and Social Studies classes. The classroom assessments are designed to mirror those on the statewide tests so the students become familiar with the assessment format.
