You will set it up so that the two equations are equal to each other.
2,200 * (2.31 * 10^x) = 1.05 * 10^y
Then depending on what you have learned you either plug in each value and check, or solve it mathmatically.
The steps for solving mathmatically:
Distribute the 2,200.
5082 * 22000^x = 1.05 * 10^y
Next divide both sides by 1.05
4840 * 20952.4^x = 10^y
I don't know if that is to the power of y or times y?
Answer:
they spend the time for swimming is 11/4 ✖ 2 =22/4
that's means in hours =5 hours 30 minutes

Answer:
94.81
Step-by-step explanation:
y = total cost used.
x = additional minutes
y = $49.95 + $0.15x
$61.20 = $49.95 + $0.15x. Subtract the $49.95 from each side.
$11.25 = $0.15x. Divide each side by $0.15
75 = x.
