For his long distance phone service, Felipe pays a $3 monthly fee plus 11 cents per minute. Last month, Felipe's long distance bill was $13.23 . For how many minutes was Felipe billed?
anyone?
You can solve this by subtracting the 3 dollars from 13.23 and then dividing by 11
i got a long decimal..
12.9572727
or 0.77?
did you convert the dollars to cents?
0.77 i think? right?
So there are how many cents in 10 dollars
ummm...
100 cents in a dollar so 100*10=?
1,000.
Good. Then add 23.
1,023.
now divide that by 11
93
Exactly. So that is how many minutes he was billed.
If you want to check your work just multiply 93 by 11 then add 3 dollars (300 cents) and convert back into dollars
yay! :D thanks so much! you think you can help me with 1 more question? then i'll be one :)
sure
ok its --- Elsa received a $70 gift card for a coffee store. She used it in buying some coffee that cost $7.53 per pound. After buying the coffee, she had $39.88 left on her card. How many pounds of coffee did she buy?
okay so first subtract 39.88 from 70
this will give you how much money she spent on the coffee in total (not the answer you're looking for)
so 30.12?
yes. now divide that by 7.53 and you will have your answer!
ahhh ok 22.59
shoot. i meant 4.
:P
ugggghhh! i put 22.59 as the first answer cause I messed up. because of that they gave me another one -_-
pls help me till I finish this thinggg. I need to get 2 in a row correct. :s
next one is, Kaitlin purchased a prepaid phone card for $25 . Long distance calls cost 24 cents a minute using this card. Kaitlin used her card only once to make a long distance call. If the remaining credit on her card is $20.92 , how many minutes did her call last?
does it mean that she originally has $25 on the phone and then after the call has $20.92?
If so then first subtract 20.92 from 25 (like the last question)
yeah I think..
then multiply the resulting answer by 100 and then divide by 24
this will be your answer
so I got 17
yep. That's what I got!
and then, Suppose that B and C are points on the number line. If =BC19 and B lies at −5 , where could C be located? If there are several locations, separate them with commas.
Did you mean BC=19?
19 :p
okay then. so take -5 and since C is 19 points away subtract 19 from -5 and also add 19 to -5
doing this will give you the two points C could be located at
kinda confusing O.o
so what is -5-19
-24
what is -5+19
14
do you see how these 2 points, 14 and -24, are 19 points away from -5?
yes
okay so your answer is 14,-24 Don't know if there should be a space in between the comma and -24 though...
now it tells me to grid these... hold on let me make a drawing.
