1. The high school performing arts program is putting on a show to raise money. They're charging adults $10 for adults and $5 for students and children. They want
to raise at least $1,500.
What is the inequality of this equation?

the first one, all those points on the line just make a strait line.

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
