7.5a+3c=663
a+c=113
Write a literal equation for c using the second equation.
c=-a+113
Substitute the value of c into the first equation
7.5a+3(-a+113)= 663
7.5a-3a+339=663
4.5a+339=663
4.5a=324
a=72
Final answer: 72 adult tickets sold
Check by finding the value of c and plugging both values in
(72)+c=113
c=41
7.5(72)+3(41)
663
True
Answer:
The store paid 6.67 times the profit made on the jeans
Step-by-step explanation:
Let the amount the clothing store pay for Jean be X
Let the amount the clothing store sells Jean be Y = X ×1.15
The profit (P) made is the difference between amount the clothing store sells Jean and the amount paid for Jean = Y - X = 1.15X - X
Profit (P) = 0.15X
X = P/0.15 = 6.67P
Therefore, the store paid 6.67 times the profit made on the jeans
To solve this problem, we must use the Time Value of Money equation.
Future Value = Present Value * (1 + interest rate per month)^number of months
F = 35,000 * (1.02)^6 = 39,415.68
A. She will have to pay $39,415.68 altogether.
To find payment in interest, we must subtract the initial loan of $35,000 from $39,415.68
39,415.68 - 35,000 = 4,415.68
B. She will have to pay $4,415.68 in interest.
