Elisa withdrew $20 at a time from her bank account and withdrew a total of $140.francis withdrew $45 at a time from his bank account and withdrew a total of $270.We need to find who made greater number of withdrawls.

Elisa withdrew $20 at a time from her bank account and withdrew a total of $140.

Number of withdrawls=Total amount withdrawn/Withdrawl amount each time

=140/20

Francis withdrew $45 at a time from her bank account and withdrew a total of $270.

Number of withdrawls=Total amount withdrawn/Withdrawl amount each time.

Elisa made more withdrawals because when you divide Elisa's total withdrawal by the amount of cash she withdrew at a time would be 140/20=7. When you compare that to Francis's withdrawal which would be 270/45=6. 7>6 so Elisa made more withdrawals than Francis.

72 - (blank) + 20 = 70 what number is the blank

Answers

$72-x+20=70 \n \n 92-x=70 \n \n -x=-22 \n \n x=22 \n \n blank=22$

$72-x+20=70 \n -x+92=70 \n -x+92-92=70-92$

Divide both sides by -1

$(-x)/(-1) = (-22)/(-1) =22$

What fraction of 130 is 80

Answers

The fraction should be $(8)/(13)$

Calculation of fraction:

Since the two numbers are given 130 and 80

We have to know about the fraction

So, the fraction should be

$= 80/ 130\n\n= 8/ 13$

Learn more about the fraction here: brainly.com/question/1786648

This is an unusual question, since they commonly ask for the percentage of the number. Nevertheless,
$(80)/(130)=(8)/(13)$
Therefore $80=130((8)/(13))$

For every $50.00. Michael earns, he saves $5. for the future. How much money will he have saved when he earns a total of $500.Question 6 options:

A. He will have saved $25.

B. He will have saved $150.

C. He will have saved $500.

He will have saved $50.

Answers

The answer is D

This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.

The proportion is as follows:

50/5 == 500/x

x is equivalent to the amount of money he has saved

You can cross multiply to get the following equation:

50x == 2500

To isolate x, you must divide both sides by 50, giving you an answer of:

x = 50

This is the same as option D

D. He will have saved $50
