The price of earbuds at the beginning of the month was $25. Over the month, the price dropped by $6, then increased by $9. What is the price at the end of the month?
To find the price at the end of the month, we need to calculate the net change in price.
The price dropped by $6, so we subtract $6 from the original price: $25 - $6 = $19.
Then, the price increased by $9, so we add $9 to the price obtained from the previous step: $19 + $9 = $28.
Therefore, the price of the earbuds at the end of the month is $28.
A scuba diver swam 96 beneath the surface of a lake. He then swam up 49 feet. How deep is he now?
To find the current depth of the scuba diver, we need to subtract the distance he swam up from the initial depth.
Starting at 96 feet below the surface, the scuba diver swam up 49 feet.
Therefore, the current depth of the scuba diver is 96 - 49 = 47 feet below the surface.
The temperature was -3 C last night. The temperature is now 15 C. What was the change in temperature
To find the change in temperature, subtract the initial temperature from the final temperature.
Final temperature - Initial temperature = Change in temperature
Change in temperature = 15°C - (-3°C)
Change in temperature = 15°C + 3°C
Change in temperature = 18°C
The change in temperature is 18°C.
Pythagoras was born in 582 BC. Isaac Newton was born in 1643 AD. How many years apart were they born
To calculate the number of years apart Pythagoras and Isaac Newton were born, we need to subtract the earlier year from the later year.
Newton was born in 1643 AD and Pythagoras was born in 582 BC. To compare the two years, we need to convert the BC year to AD.
To convert BC to AD, we subtract the year from 1.
582 BC + 1 = 581 AD
Now we can subtract the earlier year from the later year:
1643 AD - 581 AD = 1062 years
Therefore, Pythagoras and Isaac Newton were born approximately 1062 years apart.
If it is 45 F and the temperature will drop 17 in the next 6 hours, how cold will it get
To find how cold it will get, we need to subtract the drop in temperature from the current temperature.
The current temperature is 45°F, and it will drop 17°F in the next 6 hours.
Therefore, 45°F - 17°F = 28°F.
It will get to 28°F after the drop in temperature.
