Tasya [4]

Answer:

Amount = $14,024 (Approx)

Step-by-step explanation:

Given:

Amount received P = $13,500

Rate r = 7% = 0.07

Time t = 15 month = 15/12 = 1.25 = year

Discount rate = 6% = 0.06

Computation:

Maturity value = P[1+rt]

Maturity value = 13,500[1+(0.07)(1.25)]

Maturity value = $14,685.61

Time = 15 month - 6 month

Time = 9 month = 9/12 = 0.75 year

Amount = MV[1-dt]

Amount = 14,685.61[1-(0.75)(0.06)]

Amount = $14,024 (Approx)

What is the area of a room that is 3 3/4 yards long and 3 1/3 yards wide
Andreas93 [3]

Answer:

12 1/2 yd^2

Step-by-step explanation:

The area is length times width

A = 3 3/4 * 3 1/3

Change to improper fractions

A = 15/4 * 10/3

Rewriting

A = 15/3 * 10/4

   = 25/2

Changing back to a mixed number

   = 12 1/2
