Step-by-step explanation:
Answer:
year 6.6025 if there is no typo in your question and numbers are right.
Step-by-step explanation:
G = 63205 + 2500x
S = 50000 + 4500x
since 9% of 50000 = 0.09(50000) = 4500
find when G = S
63205 + 2500x = 50000 + 4500x
subtract both sides by 2500x to move x terms to the right
63205 = 50000 + 2000x
subtract both sides by 50000 to move the number to the left, so we can get like terms on each side
13205 = 2000x
divide both sides by 2000
x = 6.6025

<u>What do we know so far</u>:
*we converted the number of laps into improper fractions

<u>We want to know the number of laps in an hour</u>
⇒ so we must find the rate which ⇒ lap/hour

<u>So William can run</u> ⇒ <u>10 laps in one hour</u>
Hope that helps!
