Answer: $7
Step by step explanation: so first, we have to form any equation to show that some amount of money was added to eight dollars to get a total of fifteen dollars. Our equation becomes 8+x=15
Where eight is the origins amount, x is the amount that's added to the original amount and fifteen is the final amount.
We then move eight to the other side as a negative number
x=15-8
Therefore, x is equal to seven dollars.
Question 1:
4x+28
question 2:
18x-27
A nickel is equal to 5 cents or 0.05 dollars.
A quarter is equal to 25 cents or 0.25 dollars.
Let number of nickels be = n
Let number of quarters be = q
...........(1)
As it is given, there are 3 more nickels than quarters so equation becomes,
................(2)
Plug in the value of 'n' from (2) in (1)

= 


As
we get, 
Hence, there are 12 nickels and 9 quarters.
Answer:
5 + 25 + 75 = 105 dollars
Step-by-step explanation:
The easiest way is to just take this day by day.
day 1: 5 dollars
day 2: day1^2 = 5^2 = 25
day 3: 3 * day2 = 3 * 25 = 75
Then sum them: 5 + 25 + 75
