A school sponsors a competition for 78 students. The students work a total of 8970 math problems in 4 hrs. Each student works the same number of problems how many problems does each student work

answer

115 problems

explanation

since each student works out the same number of problems, you want to divide (total problems)/(students) to get the problems per student

the 4 hours is irrelevant here

total problems / students

= 8970 / 78

= 115 problems

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
