Ebba is buying bulk fabric. She is shopping for the best deal.

Drag the fabric in order from the least to the greatest unit cost in dollars per square yard.

To find the cost per yard, divide the cost by the amount:

p: 6.25 / 6.5 = 0.96  -->  The cost per yard is $0.96

r: 3 /4 = 0.75  -->  The cost per yard is $0.75

b: 8.1 /8.5 = 0.95  -->  The cost per yard is $0.95

s: 7.2 / 6 = 1.2  --> The cost per yard is $1.20

In order from cheapest to most expensive:

Red

Brown

Purple

Silver

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.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
