In a scale drawing, a building has a length of 15 cm. The actual length of the building is 37.5 feet. Whats the scale of the drawing?

or

Step-by-step explanation:

we know that

The scale of the drawing is equal to divide the length of a building in the scale drawing by the actual length of a building

so

That means

15 cm in the drawing represent 37.5 ft in the actual

Remember that

Convert 15 cm to ft

divide by 30.48

substitute

or

That means

1.31 units in the drawing represent 100 units in the actual

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
