Mr smith earn 1900 each week and his wife earns 1150 each week they need to set aside 300 for food 90 for gas 875 for the mortgage and 400 for savings how much money will they have left each week

answer

1385

explanation

to find the total, subtract the amount they earned by the amount they spend

total = earned - spent

earned

each week, Mr. Smith earns 1900 and and his earns 1150, so add these values together to find the total amount they earn

earned = 1900 + 1150

earned = 3050

spent

they spend money on food, gas, mortgage, and savings, so add these values together to find the total amount they spend

spent = food + gas + mortgage + savings

spent = 300 + 90 + 875 + 400

spent = 1665

total

now that we know how much they earn and spend, we can find the total

total = earned - spent

total = 3050 - 1665

total = 1385

every week they have 1385 left over
