Daniel gets a weekly $10 allowance. He has swimming class once a week and pays a $1.50 pool fee. After class, he sometimes goes out to eat with friends and spends $5 to $10. He is saving up for new swim trunks and sets aside $2.50 per week. Every few weeks, he goes to a swim meet in another town and spends $3 to $9 on bus fare.

This month, Daniel went out with friends and spent $8.50 for lunch. He went to 2 swim meets and spent $7 on bus fare each time. What are this month’s totals of his fixed and variable expenses?

fixed expenses total: $ _

variable expenses total: $ _

We have been given that Daniel's weekly allowance is $10 and we have to figure out his monthly fixed and variable expenses. To tackle this problem we have to figure out what are fixed expenses and what are variable expenses.

Fixed expenses are not going to vary as they are fixed. We have been given that Daniel has swimming class once a week and pays a $1.50 pool fee. Daniel is also saving for a new swimming trunks and sets aside $2.50 per week.

Variables expenses vary in a given range. We have been given that Daniel sometimes goes out to eat with friends and spends $5 to $10. Daniel goes to a swim meet in another town and spends $3 to $9 on bus fare.

Now let us find monthly fixed expenses first. [tex]1.50+2.50[/tex] are his weekly fixed expenses. To figure out monthly expenses we will multiply weekly expenses by 4 because a month has four weeks.

Monthly fixed expenses=[tex]4\times (1.50+2.50)=4\times 4=16[/tex]$

Now we will figure out monthly variable expenses. We have been given that Daniel has spent $8.50 for lunch and gone for two swim meets costing $7 each.

Monthly variable expenses=[tex]8.50+2\times 7=8.50+14=22.50[/tex]$
