$1, 000 after 2 years at an interest rate of 3.0% is $ round up to the nearest cent
BaLLatris [955]
This may be a simple interest computation.

Simple Interest = Principal * interest rate * term

Principal = 1,000
interest rate = 3%
term = 2 years

Simple Interest = 1,000 * 0.03 * 2
Simple Interest = 60

Total Amount after 2 years: 1,000 + 60 = 1,060

Sarah is making a wall hanging in the shape shown below.
Oduvanchick [21]

Answer:

C

Step-by-step explanation:

The area of the wall hanging shown in blue is the area of the square 8 by 8 minus the area of the cutout. Notice the cutout is a triangle? To find the total area, subtract the area of the triangle from the square.

The square has the sides 8 by 8 and its area is found as A = 8*8 = 64.

The triangle measures 4 inches by 4 inches. The area is found as A = 1/2*4*4 = 8.

Subtract the two areas.

64 - 8 = 56
