His yard business makes him $7,800 every year after accounting for expenses

Explanation:

Step 1: Determine number of yards he mows he in a year

I year has 52 weeks

He mows 6 yards once a week

Total number of yards he mows in a year=number of yards he mows in a week*number of weeks in a year

where;

total number of yards he mows in a year=unknown

number of yards he mows in a week=6

number of weeks in a year=52 weeks

replacing;

total number of yards he mows in a year=6*52=312 yards

Step 2: Determine the amount he makes in a year

Total amount in a year=amount per yard*number of yards in a year

where;

Total amount in a year=unknown

amount per yard=$30

number of yards in a year=312 yards

replacing;

Total earnings in a year=30*312=$9,360

Step 3: Determine total expenditure

The total expenditure can be expressed as;

Total expenditure=expense per yard*number of yards in a year

where;

total expenditure=unknown

expense per yard=$5

number of yards in a year=312 yards

replacing;

Total expenditure=5*312=$1,560

Step 4: Determine the net income after considering expenses

The net income can be determined using the expression;

Net income=Total earnings in a year-total expenditure in a year

where;

net income=unknown

total earnings in a year=$9,360

total expenditure in a year=$1,560

replacing;

Net income = (9,360-1,560) = $7,800

His yard business makes him $7,800 every year after accounting for expenses
