In a random survey of 250 students, 70 were in the school band. if the total student population is 1500 students, how many students are in the band?

This is a proportion problem. Start by setting up your two fractions (part over whole) and then cross multiplying

First, multiply

70 x 1500 = 105, 000

Now divide

105,000/ 250 = 420

Answer is 420

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
