Answer
23 computer
Step-by-step explanation:
if he sold 20 computers he would make 2100 which then he would need 240 more dollars to reach his goal and to find the answer you would then divide 240 by 80.
Well if the price was $100 per couple and increased by 200% then it increased by 2 times the original price. So that means the price doubled so multiply. $100 by 2 which equals $200. So the current price is now $200.
Let x = cost of desktop computer; then x - 250 = cost of laptop computer
converting % to decimals, 9% = 0.09 and 6% = 0.06
Then, 0.09x + (x - 250)0.06 = $300
0.09x + 0.06x - 15 = $300
0.15x = $315
x = $2100
then x - 250 = $1850
Proof: $2100•0.09 + 1850•0.06 = $189 + $111 = $300
Tank calculations :
Volume = 1/4(4/3 * pi * r^3)
r= 70 feet.
Volume = 1/4(4/3 * 3.14 * 70^3)
Calculating the values:
Volume = 359,000.67 ft.cubed
No we divide the actual radius by 6 to get the volume of scale model.
Hence,
6^3 = 216 times smaller.
