Question

Lorenzo has a checkbook balance of $118.00. He writes two checks, one for $9.00 and one for $84.25. He then deposits $95.00. Finally, he uses his calculator to determine his new balance. Which one of the following series represents the correct order in which he should press the keys on his calculator? A. 118 – 9 – 84.25 + 95 B. .25 = 118 + 9 / 95 C. 95 – 118 + 9 – 84.25 D. 118 – 95 + 84.25 – 9

Answer 1

If he is doing a registry, then A is the correct answer. If he only needs to know what his current balance is than it doesn't matter the order as long as deposits are added and checks are taken off.

Answer 2

Hey there!!
So lets do something I like to call "The Process of Elimination".

D is not correct because 118 -95 is not true! Lorenzo DEPOSITED 95.00 which means he added that amount to his balance and not took it away.

B is incorrect because there is no need to divide , here we are simply either taking away money from his current balance or ,we are adding.

C would be incorrect as well, because recall how i said that 95.00 dollars were "deposited" so he would add 95 , and not take it away.

That leaves us with A . Yay.....but wait, not so fast!
Lets double check shall we?

so he had 118,correct? he wrote a check for 9 dollars and 84.25. Keep in mind, that when someone writes a check, there taking money away from there account, which means subtract 9 and 84.25 from 118. 
And then , lets not forget that 95 he deposited.
Deposit means add.

So yes! A is the correct answer!

Hope my explanation helped :)
