Can someone please answer correctly plz

A negative number means cups are being used and a positive number means cups are being delivered to the shop.

2329 paper cups are left by the end of the week

On Thursday anywhere from 100-400 cups were used, I found this by looking at the number of cups used the day before and the day after.

Step-by-step explanation:

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

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

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