If f = price of filing cabinet and c = price of cupboard we can make up the equation
2f + 4c =800
we also know that f = 3c, so can substitute that into equation
2(3c) +4c = 800
6c + 4c = 800
10c = 800
<u>c = 80</u>
<u>f = 240</u>

Step-by-step explanation:
When two lines are perpendicular to each other, their slope are the negative reciprocal to each other. (so you flip them and change the sign)
<u>8.60</u> = <u> X </u>
50 100
"Percent" means "out of one hundred" (Latin).
Multiply the top by two, since 100 is twice 50, and the fractions will be equal.
The answer is 17.2%.
