Answer:
r= -1/5
Step-by-step explanation:
Step 1: Remove the parentheses (5r-10= -51)
Step 2: Move the constant to the right-hand side and change the sign (5r= -51 + 50)
Step 3: Calculate the sum of -51 +50 (5r = -1)
Last Step: Divide both sides by the equation by 5 (r = -1/5)
1) montly rate, r = 5% / 12 = 0.416% = 0.00416
2) capital, C = $ 450 = present value
3) time = 11 years => number of periods = 11 * 12 = 132
4) Formula: FV = C * (1 + r) ^ (number of periods)
5) Calculation: FV = $450 * ( 1 + 0.00416)^(132) = $ 779.07
Answer: $ 779.07

Answer:
- Blueberry pie costs $9, lemon meringue cost $14
Step-by-step explanation:
<u>Set equations:</u>
- 13x + 12y = 285
- 3x + 12y = 195
<u>Solve by elimination. Subtract the second equation from the first:</u>
- 13x + 12y - 3x - 12y = 285 - 195
- 10x = 90
- x = 9
<u>Find the value of y:</u>
- 3*9 + 12y = 195
- 12y = 195 - 27
- 12y = 168
- y = 168/12
- y = 14
