Bob the best way to approach this is to first take a look At the key elements of the problem.
Always using information from the question helps you arrive at the answer. Notice that Mae Lin Weekly earnings are based on salary plus commission. This helps us to write an equation for this problem
weekly earnings= salary + commission
The problem clearly states what the salary is. However you have to calculate the commission. The Commission is only a percentage of wht Mare sold. So the commission is calculated based on the following equation
Commission= Commision rate (%) x amount sold
The Commision rate is the percentage in this problem is 6.25%. Remember to express percentage as a decimal, simply take the percent and divide by 100. So 5% would be 0.05 Or 5/100.
Here is a summary of how to solve the problem.
1. Calculate the Commision based on the details for the problem.
2. Calculate the weekly earnings by using the first equation Introduced.
Sample Problem
Mae Lin’s weekly salary is $10 plus a 5% Commisio. How much does she earn on a week she sold $100.
step 1 Calculate Commision
Commission= 0.05 x 100= $5
step 2 calculate weekly earning
weekly earnings= $10 +$5
i hope this explanation is helpful
