I came across with this last problem that I don't get on this sheet.

Dan's uncle ask him to come work for him at his men's clothing store. He will pay him 5% on his first $1000 in sales and 8% on sales above $100. How much will Dan earn if he sells $2500 in merchandise?

Please who work.
I got $500

It appears you have a typo. You probably mean 8% on sales above $1000, since he earns 5% on the first $1000.

So, if he sells $2500, that's $1000 + $1500, so he gets

5% of $1000 plus 8% of $1500, or
.05 * 1000 + .08 * 1500 = 50 + 120 = $170

How ever did you get $500? That's 20% of the whole amount!

.05 (1000) + .08 (2500-1000)

= 50 + 120 = 170

To solve this problem, we need to calculate the earnings in two steps.

Step 1: Calculate the earnings on the first $1000 in sales
Dan will earn 5% on his first $1000 in sales.

Therefore, the earnings on the first $1000 can be calculated as:
Earnings_on_first_1000 = 5% of $1000 = 0.05 * $1000 = $50

Step 2: Calculate the earnings on sales above $1000
Dan will earn 8% on sales above $1000.

Sales above $1000 = Total sales - $1000
Sales above $1000 = $2500 - $1000 = $1500

Therefore, the earnings on sales above $1000 can be calculated as:
Earnings_on_sales_above_1000 = 8% of $1500 = 0.08 * $1500 = $120

Now, we can find the total earnings by summing up the earnings from step 1 and step 2:
Total_earnings = Earnings_on_first_1000 + Earnings_on_sales_above_1000
Total_earnings = $50 + $120 = $170

Therefore, if Dan sells $2500 in merchandise, he will earn $170.
