Is a problem solving method that uses that fact that any number or expression can be multiplied by one without changing it's value.
Answer:
$7.50
Step-by-step explanation:
<u>If she is not a member:</u>
to print 350 pictures, she will pay 0.2 * 350 = $70
<u>If she IS a member:</u>
to print 350 pictures, she will pay 0.15(350) + 10 = $62.5
THus, the amount she saves is 70 - 62.5 = $7.50
Answer: y=3/4x+3/2
Step-by-step explanation:
Let's solve for y.
3x−4y+6=0
Step 1: Add -3x to both sides.
3x−4y+6+−3x=0+−3x
−4y+6=−3x
Step 2: Add -6 to both sides.
−4y+6+−6=−3x+−6
−4y=−3x−6
Step 3: Divide both sides by -4.
−4y/−4= −3x−6/−4
y=3/4x+3/2
Answer:
27 years
Step-by-step explanation:
P is measured in thosands therefore, P will have a value of 120
so it would be...
120=80e^0.015t
80e^0.015t=120
e^0.015t=120/80=3/2=1.5
e^0.015t=1.5
0.015t= In(1.5)
t=In(1.5)/0.015
∴ t≈27.03 round it to 27 years
It would be greatly appreciated if you gave me the brainlest
