Which values of p and q result in an equation with exactly one solution?
px + 50 = −2x + q

(select all that apply)
a)p = 2p and q = −2
b)p = −2p and q= −50
c)p = −2p and q = 50
d)p = 50 and q = 50

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
