Answer:
Yes
Step-by-step explanation:
Since Jenny makes a profit of $2 for each bar of chocolate that she sells, if she sells a total of 500 chocolate bars, her profit would be:
Profit for 500 chocolate bars = profit for each chocolate bar * 500 bars
Profit for 500 chocolate bars = $2 per bar * 500 bars
Profit for 500 chocolate bars = $1000
Also she want to buy a laptop worth $998. This would be possible after selling 500 bars because $1000 > $998. After buying the laptop she would have $2 remaining ($1000 - $998)
Answer:
3divded by 3 plus 3 minus 6
Step-by-step explanation:
Annual Statistics Concerning Water Bottles in the United States
Bottles Purchased: 5 * 10^10
Bottles Recycled: 8.333333333 * 10^9
50/8.333333333 = approx 6
The number of bottles purchased is 6 times larger than those that were recycled.
Annual Statistics Concerning Coastal Erosion
California Coastal Erosion: 3 * 10^1
Louisiana Coastal Erosion: 1 * 10^3
(10 meters = 1000 centimeters)
1000/3 = 333 1/3
The coastal erosion in Louisiana is 333 1/3 times greater than coastal erosion in California.
Size of the Sun and Earth
Radius of Sun: 6.955 * 10^8
(695,500 km = 695,500,000)
Radius of Earth: 6.371 * 10^6
695.5/6.371 = approx 109.2
The radius of the Sun in 109.2 times larger than that of the Earth.
Number of Brain Cells
Ant Brain Cells: 2.5 * 10^5
Human Brain Cells: 1 * 10^10
(10,000 mil = 10,000,000,000)
100,000/2.5 = 40,000
A human has 40,000 times the amount of brain cells an ant has.
You can set up an equality:
40/160 = 225/x
Cross multiply:
40x = 160(225)
Evaluate:
40x = 36000
Isolate x:
x = 900.
So, 900 batteries are required for 225 calculators.
