Apencil costs $0.45, an eraser costs $0.30, and a pencil sharpener costs $0.30. what is the cost of 3 pencils, 2 erasers, and 1 pencil sharpener?

Hi!

We know the prices of one pencil, one eraser and one pencil sharpener, which are $0.45, $0.30 and $0.30, respectively. Given that, we will find the cost of 3 pencils, 2 erasers and 1 pencil sharpener like this:

3 * 0.45 + 2 * 0.30 + 1 * 0.30 = 1.35 + 0.60 + 0.30 = 2.25

The cost of 3 pencils, 2 erasers and 1 pencil sharpener is $2.25.

Hope this helps!

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
