Question

A salesman receives a fixed salary of $500 per week. In addition he is paid 12% of all sales over $1000. Write the formula that describes how his weekly salary, s, depends on his weekly revenue, r. (The revenue is the amount of money he collects by selling the goods.)

Answer 1

Answer:

y = s + 0.12(r-1,000)

Explanation:

Given:

Fixed salary (s) = $500 per week

Additional income = 12% of sales over $1,000

Sales (r) = r

Total weekly salary (y) = ?

Computation of total weekly salary:

Total weekly salary (y) = Fixed salary + Additional income

Total weekly salary (y) = $500 + 12% of sales over $1,000

Total weekly salary (y) = $500 + [12/100] × [sales - $1,000]

Total weekly salary (y) = $500 + 0.12 × [sales - $1,000]

Additional equation:

y = s + 0.12(r-1,000)
