Answer:
C.) 21
Step-by-step explanation:
d = 22.5n + 27.5
Where d is the total amount of money earned and n is the number of items sold
Substitute:
500 = 22.5n + 27.5
We can substitute 500 for d because 500 is the total amount of money Kathryn wants to earn
Solve:
500 = 22.5n + 27.5
Subtract 27.5 on both sides:
500 = 22.5n + 27.5
-27.5 -27.5
472.5 = 22.5n
Divide by 22.5 on both sides:
472.5 = 22.5n
/22.5 /22.5
21 = n
Therefore, Kathryn must sell 21 items to make $500.
Answer:
<u>The answer is that this month’s fuel oil bill exceed last month’s bill by US$ 27.10</u>
Step-by-step explanation:
Let's review extensively the Rick and Koby's bank account activity to answer the question correctly:
Previous balance US$ 528.76
Deposits this month:
Automatic deposit US$ 400.oo
Interest earned US$ 3.56
Balance = 932.32
Withdrawals this month:
Checks processed US$ 416.79
Fuel oil bill = x
Balance = US$ 228.58
For calculating the fuel oil bill, we solve the following equation:
932.32 - 416.79 - x = 228.58
515.53 - x = 228.58
- x = 228.58 - 515.53 (Subtracting 515.53 at both sides)
- x = - 286.95
<u>x = 286.95</u>
<u>286.95 - 259.85 = 27.10</u>
<u>This month's fuel oil bill was US$ 286.95 and exceeds by US$ 27.10 last month's bill.</u>
