Answer:
$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.
