In the fifth grade at lenape elementary school, there are 4/5 as many students who do not wear glasses as those who do wear glasses. if there are 60 students who wear glasses, how many students are in the grade.

108 students

Given:

In the fifth grade at Lenape Elementary School,

Question:

How many students are in the grade?

The Process:

Let us prepare a model for students who wear glasses.

Then we make a model for students who do not wear glasses. As we know above, there are ⁴/₅ as many students who do not wear glasses as those who do wear glasses.

Let us calculate the number of students who do not wear glasses.

We crossed out 5 and 60.

Finally, let's add up the number of students who wear glasses and do not wear glasses to find out how many students are in the grade.

Keywords: in the fifth grade, Lenape Elementary School, there are 4/5 as many students, who do not wear glasses, 60 students who wear glasses, how many students, in the grade, model

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.
