It’s d, looks like you got it already! With ratios, just pay attention to not only the numbers but order of the words as well, so you can be sure the ratio follows the problem.
Answer:
A. P - 0.3P
Step-by-step explanation:
Given the price of the computer is P dollars and it’s on sale for 30% off.
That’s
30% /100% x P
0.3 x P
0.3P
Savings being offered on the computer is therefore
P - 0.3P
This is because 0.3P is the discounted amount and to get the sale on amount , you subtract the discounted amount from the original price P
The ratios are equivalent because you multiplied 18:4 by 2&3. And also you divided it by 2. I had the same homework!
Answer:
Answer (a) is correct
Step-by-step explanation:
This is not the same function that was given to you in the problem.
As you have typed it, this function is linear. The one in the homework problem is exponential.
We will ignore the linear function h(t) = 0.32 - 0.5t.
We will focus on h(t) = 0.32 - 0.5^t.
If t = 0, then 0.5^t = 0.5 ^0 = 1, and so h(0) = 0.32 - 1 = -0.68 => (0, -0.68)
Continuing with a few other t values chosen at random:
h(1) = -0.18
h(2) = 0.07
Notice that h is increasing as x increases!
h(4) = 0.2575
and so on.
answer A is the correct one.
h(1) = 0.32 - 0.5^1 = 0.32 - 0.5 = -0.18
