M. Hernandez plans to purchase shades for her 8 windows and would like to keep the cost under $1,100. There will be an installation fee of $160. What is the highest price she can pay per shade to the nearest whole dollar?

117

Step-by-step explanation:

1,100 - 160 = 940

940 ÷ 8 = 117.5

you round down to 117

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
