Madison has x dimes and y nickels, having at least 18 coins worth no more than $1.50 combined. No more than 6 of the coins are dimes and a minimum of 18 of the
coins are nickels. Solve this system of inequalities graphically and determine one
possible solution.

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.
