24.5=-2.5c-4c
24.5=-6.5c
49=-13c
3.77=-c
c=-3.77
I beleive that the way to figure this out is since 20 time 5 is 100 you will just need to time 815 times 20 and you should get the total amount of money you made that year so your answer would be 16,300 I hope that helps ^-^
Answer:
Betsy will save $121 in 5 weeks.
Step-by-step explanation:
We can see that Betsy's savings are 3 times the saving of her last week. We can see that this is an geometric sequence as 1,3,9,..
To find the sum of our geometric sequence we will use 
, where n is number of terms we are taking sum of, a is first term of sequence and r is common ratio of the sequence.
Therefore, Betsy will save $121 in 5 weeks.
Answer:
It does show direct variation.
Step-by-step explanation:
Every hour, you receive $8.50. This doesn't change throughout the entire table. On a graph, this would look like a line going through the origin, with points at (1, 8.5). (2, 17), (3, 25.5), and so on.
Answer:
6/50 simplified to 3/25
Step-by-step explanation:
step 1 Address input parameters & values.
Input parameters & values: The decimal number = 0.12
step 2 Write it as a fraction
0.12/1
step 3 Multiply 100 to both numerator & denominator
(0.12 x 100)/(1 x 100) = 12/100
It can be written as 12% = 12/100 or 12/100
step 4 To simplify 12/100 to its lowest terms, find LCM (Least Common Multiple) for 12 & 100.
4 is the LCM for 12 & 100
step 5 divide numerator & denominator by 4
12/100 = (12 / 4) / (100 / 4)
= 3/25
3/25 is a simplest fraction for the decimal point number 0.12
