Dominic's three daughters want to take gymnastics this year. It costs $90 per month per child. How much does Dominic need to budget for a year (12 months) of gymnastics for his daughters?

$3,240

Step-by-step explanation:

To find the amount of money that Dominic will need to pay for gymnastics for his three daughters, first you have to multiply the cost per month per child for 12 months to know the cost per year per child:

$90*12=$1,080

Then, you has to multiply the cost per year per child for 3 that is the number of daughters:

$1,080*3=$3,240

According to this, Dominic need to budget $3,240 for a year (12 months)

of gymnastics for his daughters.

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.
