Answer:

a)  C = 250 + 1.25n

b) 1800

c) 300

Step-by-step explanation:

a) To write the equation for these problems, let's establish the constant, $250, since we are given that $250 is a FIXED cost, meaning no matter how many brochures we print, we will have to pay $250. Then, we have to pay $1.25 for each brochure, so for n amount of brochures, so we have 1.25*n. Putting it together, we have the fixed cost + the cost of producing n brochures, C = 250 + 1.25C

b) The cost of printing 2500 brochures can be found by pluggin number into the equation above. C = 250 + 1.25*2500 = $1800

c) This is the opposite question, since 625 is the final cost, we plug it into the final cost, 625 = 250 + 1.25*n. Solving gives n = 300

1. Over 3 years, how much more does $3000 in a savings account with an APR of 3.2% compounded
Sedbober [7]

Answer:

$1080

Step-by-step explanation:

((3000 \times 0.032) \times 2) \times 3 = 576

convert % to decimal by multiplying 3.2%x100=0.032

then multiply by initial amount 3000x0.032

then multiply by 2 because it's compounding semiannual

then multiply by 3 because it's over a 3 yr period

do the same for the quarterly compound but multiply by 4 because it's quarterly

((3000 \times 0.03) \times 2) \times3 = 1080

over a 3 yr period the quarterly compounded amount will earn:

1080 - 576 = 504

$504 more than the account compounded semiannual
