The answer is actually 42. Not 20.
You replace each x with 3
5(3)+9(3)
That 3 right next to the five means you multiply not add.
15+27=42
Brainliest my answer if it helps you out?
P0 = 1000
<span>(A) pt = 1000 + 90t ; 1000 + 90 + 90 + 90 ... </span>
<span>(B) pt = 1000 * 1.03^t ; ((10000 * 1.03) * 1.03)..</span>
Answer:
Time required to save 1000$ is 100 hours
Step-by-step explanation:
Money wasted = 1000$
savings = 10.00$ per hour
using unitary method
if i am saving 10.00 $ per hour then let in t hours i save 1000$
⇒ 10.00 x t = 1000
dividing above equation by 10 we get,
⇒ t = 100 hours
Therefore, Time required to save 1000$ is 100 hours
