A company can buy packages of 500 sheets of paper for $4. At that rate, how much paper can be bought for $2000? Group of answer

Alexandra [31]

Your answer is 250,000. There are two ways to do this problem.

1) Solve 500/4 to find out how many sheets of paper you get per every dollar. — Your answer is 125 sheets for $1. Then you multiply that answer by 2000, and get 250,000. Which means you get 250,000 sheets of paper for $2000.

2) You can divide 2000 by 4 & that gets you 500, you can then multiply that by 500 & you will get 250,000.

Hope this helps.

Mumz [18]

Answer:

$\frac{28}{3}=t$

Step-by-step explanation:

$\frac{4}{3}=\frac{t}{7}$

Use cross products to simplify the equation. Multiply the denominator of the second fraction by the numerator of the first fraction, and the denominator of the first fraction by the numerator of the second,

$(4)(7) = (3)(t)$
