Question

Help plz!!!

You and some friends have raised $250 to help make a video for a local contest. You need $35 to buy videotapes and it costs $45 per day to rent the video camera. Write and solve an inequality to find the possible number of days you can rent the video camera.

Answer 1

Okay, so the total has to be \(\leq 250\) since that is all of the money you have. And since it costs 45 dollars per day that is the same as \(45d\) where d is the number of days. You also need to pay 35 dollars to buy videotapes. This makes the inequality \(250\geq 45d+35\). Do you know how to solve this for the variable d?

Answer 2

So its 4.7 ≥ x

Answer 3

Would that be 4 days?

Answer 4

no it would not be

Answer 5

You rounded up instead of down

Answer 6

because you should remember the money you spent on the tapes

Answer 7

which is 35

Answer 8

as it says, the possible number of days.

Answer 9

?, if it's 5 days, then it goes over $250

Answer 10

it isnt five days

Answer 11

I was wrong, you can't round up anyways. it's 4.7 or nearest is 4 days

Answer 12

Okay, I get it now.

Answer 13

wouldnt it be less than four days?

Answer 14

No, you subtract 35 then divide you get 4.777777778 4 is less than that

Answer 15

well alright

Answer 16
