Step-by-step explanation:
so let's assume they both sold for 100 each the first article sold for 10% laws there by cost of article is 111.11 rounded the second article made 25% profit so cost must be 80 total cost is 8.89 or 5% profit I'm so sorry if im wrong
97 rounds up to 100
78 rounds up to 80
100x80= 8,000
estimate=8,000
97x78=7,566
product=7,566
I think this is how you do it
8x + 84 = 500
8x = 416
x = 52
So if he wants to earn more than 500 dollars, he needs to make more than 52 dollars a week.
