Answer:
B
Step-by-step explanation:
(1/5)b-5((2/5)a-(1/10)b)+4a
(1/5)b-(10/5)a+(5/10)b+4a
2a+(7/10)b
If you pay attention 2 goes into 8, 10, & 12 and it looks like they all have one C. So what do you think it is lol?(:
12.57 * 4.11 = 51.66
1257 *remove the decimal and treat the numbers as whole numbers.
<u> x 411</u>
1257 * 1 x 1257
12570 *10 x 1257
2800 *400 x 7
20000 *400 x 50
80000 *400 x 200
+ <u>400000 </u> *400 x 1000
516627
516627 is the product of 12.57 and 4.11 without their decimal points.
516627. the decimal point must be moved 4 places because the total count of numbers after the decimal is 4.
from 516627 to 51.6627 ; round to the nearest hundredth 51.66
For this case we have the following equation:
Where, the variables are defined as:
c: the cost per page
t: the total cost of editing 25 pages
From here, we must replace the value of t = 66.50 in the given equation:
Then, we clear the value of c.
We have then:
Answer:
The best quality of editing that Maria can get done for a maximum of $ 66.50 is:
