To solve the problem "56 is what percent of 707" students used the following models
Noah's model:
+7
0 7 14 21 28 35 42 49 (56 43 70
0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100%
Divide 70/10=7, since 100%/10=180o.
So each # is another 10% 56 is at 80%
Carey's Model
Since 35 is half
i of 70 and 7
1 42 49 56
is 10% of 70,
t an 80% + I started at 35
and jumped 3 .
0% 10%
times to get to 56.
35
S
50%), +102
+0%.
100%
7. Use either students method to model 40% of 240.
8. Use a model to estimate what percentage is closest to 65 out of 85.

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.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
