Mama had several notebooks. if she give 13 notebooks to each of her children, she will have 8 left. if she give 15 notebooks to each of her children, she will have nothing left. what is the smallest number of notebooks and children does mama have?

Children=4

Notebooks=60

It said mama's got an amount of books, so you can transform this into a equation

X=children

Notebooks= 13x +8

Notebooks= 15x

Now you just establish a system of equations, thus notebooks=notebooks

13x + 8= 15x

2x=8

X= 4

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.
