Trever spends $240 in 3 weeks how much will he spend in 8 weeks?

djverab [1.8K]

Answer:

He will spend $560 in 8 weeks

Step-by-step explanation:

So 260 for every 3 weeks how much will he make in 8 weeks

so 240+ 240

cause he makes 240 every 3 weeks

so he will make 480 in 6 weeks.

then to get how much he makes in 1 week you divide 240 into 3

so 240 divided by 3 equals 80 So he makes 80 in 1 week.

So 240+240+80=560

So he make $560 in 8 weeks

A math textbook is 1 1/4 in. thick. how much shelf space is needed for 30 copies of the book?

inysia [295]

Hello!

You have to multiply 1 1/4 by 30 because each math book is 1 1/4 in. thick, and 30 books is 1 1/4 by 30. First change 30 and 1 1/4 to an improper fraction.

$\frac{30}{1} \times \frac{5}{4} = \frac{150}{4} = 37 \frac{1}{2}$

$\framebox{37 1/2 inches}$
