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.
