Answer:
If Dan makes $3,500 per month, and he spends $1,250, he has $2,250 left in his monthly budget.
Explanation:
Dan's personal budget consists of his fixed income and his fixed expenses. Fixed income consists of his salary, while fixed expenses are made up of the expenses of car payment, phone payment and rent.
In order to determine how much money he has left in his monthly budget, Dan must subtract the fixed expenses from his fixed income. He must then perform the following calculation:
#3500 - (300+50+900)
#3500 - 1250: 2250
As we can see, Dan has $2,250 left in his monthly budget.
