Estelle treated her sister to lunch while visiting her in Lowell. Their lunch cost $80, and the sales tax in Lowell is 15%. If Estelle left a 15% tip on the $80, how much in total did she pay?

Estelle paid $104 in total.

Step-by-step explanation:

15% of $80.00 is 12. So add 12 two times to 80 because of 15% sales tax and 15% tip.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

so, after 10 years : rick has $1400 and sally has $1500
