Answer:
Step-by-step explanation:
<u>Given</u>
- SP = $25
- SP = CP + 25% = 1.25CP
<u>Find cost price for each memory card</u>
- 25 = 1.25CP
- CP = 25/1.25
- CP = 20
<u>The store paid for 50 memory cards</u>
6*30 = 180
8*20 = 160
9*10 = 90
180+160+90 = 430 stickers
Answer:
A a. 25 minutes
Step-by-step explanation:
Let x = time in minutes.
Aquarium I contains y water at time x.
y = 4.6 + 1.2x
Aquarium II contains y water at time x,
y = 54.6 - 0.8x
We want the amounts of water to be equal, so we set the right parts of the equations equal and solve for x, the time in minutes.
4.6 + 1.2x = 54.6 - 0.8x
Subtract 4.6 from both sides.
Add 0.8x to both sides.
2x = 50
Divide both sides by 2.
x = 25
If your looking for the sequence in which the numbers are divided by to find the next number it would be 4.
48 divided by 4 is 12, then 12 divided by 4 is 3....
