if 40% of the students in the class are boys , and if there are 18 girls in the class , then how many students are in the class?
chubhunter [2.5K]
30

60% were girls so you put this as a ratio

60/100= 18/x

You calculate x to determine the total number which would equal 30.

When she graduates college Linda will owe 43,000 in student loans. The interest rate on the federal Liana is 4.5 % and the rate
Amanda [17]

Answer:

federal loan amount = $29,000

private loan amount = $14,000

Step-by-step explanation:

Total amount is 43000

Let amount in federal be f

and

amount in private be 43,000 - f

Interest rate at federal is 0.045

Interest rate at private is 0.02

THus, we can form the equation shown below and solve:

f(0.045) + (43,000 - f)(0.02) = 1585

0.045f +860 - 0.02f = 1585

0.025f = 725

f = 29,000

and on private = 43,000 - 29,000 = 14,000

Hence

federal loan amount = $29,000

private loan amount = $14,000
