Answer:
598 books
Step-by-step explanation:
Let x be the number of books in the 3rd pile. We will have then:
1st pile: 2x + 10
2nd pile: 2x
3rd pile: x
3000 = (2x + 10) + (2x) + (x)
3000 = 5x + 10
3000 - 10 = 5x
2990 = 5x
2990/5 = x
x = 598 books in the third pile!
We can check that:
3000 = 2*598 + 10 + 2*598 + 598
3000 = 1196 + 10 + 1196 + 598
3000 = 3000 CHECK!
Her insurance premiums are 150 per month.....there is 12 months in a year....so in 1 year, her premiums totaled : (150 * 12) = 1800
she paid a $ 500 deductible
she paid 20% of $ 3000 for the accident..
0.20 * 3000 = $ 600
therefore, her total healthcare expenses for 1 yr totaled :
1800 + 500 + 600 = $ 2900 <==
