How much will Tiana earn after 10 weeks?
Round to the nearest dollar. And here are the potential answers...
To start, we need to focus on the most important information: Tiana's weekly pay.
In the first week, she gets paid 100 buckaroos. In the following weeks, she'll get paid
75% of each previous week's pay.
When her salary drops below $25, she'll get paid a steady amount of $25.
The easiest way to solve this problem is to make a chart of how much she makes each week,
starting with week 1 and ending with week 10.
Week 1, she makes $100. Week 2, she makes $75, which is 75% of $100.
This pattern stays the same and by week 6, she's earning $25.
She will continue to make $25 for the next weeks till she hits 10 weeks.
Now that you've got a list of her salaries
over all 10 weeks, just add them up... and we get $430.
Choice E is the correct answer.
