The cost of watching videos on a website is represented by C(a) = 3.00a + 4.00, where a is the number of videos watched. The cost is increased by $15.00 if the downloading feature is enabled. Identify the new function H(a) for the cost of watching downloadable videos and the transformation that has been applied. A: H(a) = 3.00a + 19.00; shift 15 units up
B: H(a) = 18.00a + 4.00; shift 15 units up
C: H(a) = 18.00a + 4.00; shift 15 units down
D: H(a) = 3.00a + 19.00; shift 15 units down

step-by-step explanation:

a is the correct

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
