A scientist recorded the amount of substance X present in an ongoing chemical reaction. This table gives the amount of substance X over the first 10 minutes. The data can be modeled using an exponential function. Time (min) 2 4 6 8 10
Substance X (g) 15.6 13.2 11.8 11.1 10.2

Based on the data, which measurement is closest to the amount of substance Y that will be present after 20 minutes?

0 g

5.1 g

6.0 g

7.2 g

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
