Dominic's two daughters both 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 both daughters?
The total cost for one child for a year of gymnastics is $90/month x 12 months = $1080.
Since Dominic has two daughters who want to take gymnastics, the total cost for both daughters for a year would be $1080 x 2 = $2160.
Therefore, Dominic needs to budget $2160 for a year of gymnastics for both daughters.
