Answer:
His yard business makes him $7,800 every year after accounting for expenses
Explanation:
<em>Step 1: Determine number of yards he mows he in a year</em>
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
<em>Step 2: Determine the amount he makes in a year</em>
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
<em>Step 3: Determine total expenditure</em>
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
<em>Step 4: Determine the net income after considering expenses</em>
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
