Step-by-step explanation:

Step 1: Value of sales

Express the total value of sale the shoe salesman makes as follows;

Total value of sales=number of shoes sold×price per shoe

where;

Number of shoes sold and price per shoe=2 pairs each at $80

number of shoes sold a and price per shoe=3 pairs each at $70

replacing;

Total value of shoes sold=(2×80)+(3×70)=$370

Total value of shoes sold=$370

Step 2: Calculate how much the shoe salesman earns

The expression for how much the shoes salesman will earn is as follows;

A=r×c

where;

A=total amount of the shoe salesman income

r=commission rate

c=total value of sales

In our case;

A=unknown

r=20%=20/100=0.2

c=$370

Step 3: Substitute values in the expression

A=20% of $370

A=0.2×370

A=74

The shoe salesman will earn a commission of=$74
