Another brand of sheets is on sale 30% off with a regular price of $18.00 per sheet. Which is a better deal, the previous example or this one? Explain
Answer:
It would cost 12.60 dollars for the company in the problem. If you could send the other company's deal I could write the answer in the comments.
Step-by-step explanation:
100% - 30% = 70%
70% to demical = 0.7
So, I would do...
18 times 0.7 to get 12.6
The answer you get would be $12.6
The formula I used for this was...
( T ) * ( 1 - S ) = F
T is the Total cost
S is the amount of sale in percent to decimal form
F is the final amount
Hope this helps :)

Ricardo has 2020 coins, some of which are pennies (1-cent coins) and the rest of which are nickels (5-cent coins). He has at least one penny and at least one nickel. What is the difference in cents between the greatest possible and least possible amounts of money that Ricardo can have?
Answer:
The lowest amount would be (1 x 5) + (2019 x 1) = 2024 cents, or $20.24
The highest amount would be: (1 x 1) + (2019 x 5) = 10,096 cents, or $100.96
100.96 - 20.24 = 80.72
The difference in cents between the greatest possible and least possible amounts of money Ricardo can have is $80.72.

A navy submarine descended at a rate of 4 feet per second. a. Write the descent rate as an integer. b. Write an expression to find the submarine's elevation after 5 minutes.
Answer:
1200
Step-by-step explanation:
Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute. Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.
