Given:
Total income form tips = $131
His tips consisted of $1 bills and $5 bills only.
Total number of bills = 47
To find:
The number of $5 bills.
Solution:
Let x be the number of $1 bills and y be the number of $5 bills.

Total income : ...(ii)
Subtract (ii) from (i), we get
Therefore, the number of $5 bills is 21.
Take the total cost and subtract the registration fee.
56.25-12.5=$43.75
The remainder is what was spent on swim classes so divide by the cost of the swim classes.
$43.75/8.75=5 swim classes
Answer:
Step-by-step explanation:
Earth volume is approximately V = (4/3)πr³, and
Uranus volume is approximately V = (4/3)π(4r)³, or (4/3)π*64*r³
Comparing these two results, we see that the volume of Uranus is approximately 64 times greater than the volyume of Earth.
It is rational because it is a terminating decimal. Have an amazing day!
