Sandra's total earnings were $500, of which $350 was salaried, so she earned $150 in commissions (500-350). Since she receives 5% commission, that means $150 is 5% of her sales. 100% of her sales would be 20 times that, which is $3000.

Say that she made sales with a value of n

Then we can get an equation: total = base + commission

total = 500, base = 350, so commission is 150

From this we can say 150 = 0.05n

and multiply by 20 to solve for n

Thanks, but i don't understand how to solve ones that have a varable.
If i did ur problem right I got the answer $150.

Is there a way u can explain it better 4 me. Thanks

Can u explain this better please.

How? The total sales is not You need to solve for in the equation. Do you know how to solve simple algebraic equations?

The equation can be written as





Now, do as e^(i*pi) said and multiply both sides by 20.
