Answer:
a. $65
b. $(50 + 15x)
Step-by-step explanation:
A. From the question, we are told that the first 2 GB of data costs $50 while the subsequent extra GB cost $15 per GB
so for 3 GB, the normal $50 is charged for the first 2 GB while an extra $15 is charged for the extra 1 GB
so, the total amount charged for 3 GB will be $50 + $15 = $65
B. Amount to be paid in a month where x GB is used over the normal
Firstly, she will pay the $50 , then for the extra she will be paying $15 * x = $15x
So the amount to be paid will be;
$50 + $15x = $(50 + 15x)
1/6 thats it u cant simplify
Answer:
Devon
Step-by-step explanation:
lets use t=1 to compare
1. -5(12t+9)
if t = 1, -5(12+9) = -5(21) = negative number
2. 2(-6t-8)
if t = 1, 2(-6-8) = 2(-14) = negative number
3. -6(-2t+18)
if t = 1, -6(-2+18) = -6(16) = negative number
4. (-4(-3t-2)
if t = 1, -4(-3-2) = -4(-5) = 20 positive number
