Astore is having a sale on chocolate chips and walnuts. for 4 pounds of chocolate chips and 8 pounds of walnuts, the total cost is $33. for 2 pounds of chocolate chips and 3 pounds of walnuts, the total cost is $14. find the cost for each pound of chocolate chips and each pound of walnuts.

w = 2.50

c = 3.25

Step-by-step explanation:

Use system of equations and solve

c = chips, w = walnuts

eq1 > 4c + 8w = 33

eq2 > 2c + 3w = 14

modified eq 2 > 4c + 6w = 28

eq1-eq2 = 2w = 5

Solving:

w = 2.50

c = 3.25

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.
