Answer:
Correct cost for the cell phone monthly plan = 54.2$
Explanation:
Price for monthly plan = 58.95$
Discount = 4.75 $
New cost found out by Sam = 11.45$
Discount considered by Sam = 58.95 - 11.45 = 47.5$
So, Instead of considering discount amount of 4.75$ Sam accidentally considered 47.5$, so he got 11.45$ as new cost for the cell phone plan.
Actual cost = 58.95 - 4.75 = 54.2$
Correct cost for the cell phone monthly plan = 54.2$
6.21 --subtract 1.05 from 7.26
Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.
For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>
