you do 15.0 x 4.0 and that would give you the answer of 60.
the bridge is 60m above the water.
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.
I’m 99% sure it’s D because you would add both those numbers to equal his debt that day
1). 1n+5-1
N=26
2). n2+n n2+n
n3+n2+n
