Answer:
16 months
Step-by-step explanation:
Look at the chart on the left and look at what number of months is closest to 15,000. 16 is at 15,034
To solve mathematically:
y is the balance that his account would have. You want to find the amount of months it will take before it becomes $15,000, so 15000 is your y value
15,000= - 440.91x+22,060.7
-7,060.7= - 440.91x Subtract 22,060.7 from both sides
16.0139=x Divide both sides by - 440.91
You would do 3x60=180 since there is 60 minutes in each hour then dives 180 and 20 which gives you 9 batches of cookies. Hope this helps!
Answer:
The correct answer is 9x + 7 y
147 where Ashley works for x hours as lawn mower and y hours as babysitter per week.
Step-by-step explanation:
Ashley works in two different jobs namely mowing lawns and babysitting.
Let Ashley mow lawn for x hours and babysit for y hours in a week.
Ashley's earning for every hour she mow is $ 9. Total earning mowing lawn is $ 9x.
Ashley earns $7 for every hour she babysit. Total earning babysitting is $ 7y.
Total earning per week $ (9x + 7y).
Ashley's earning per week is at least $147.
∴ The required inequality to describe the above case is 9x + 7 y
147.
