A mobile phone carrier charges an extra fee if a customer uses more than 500 minutes each month. Tom has already used 230 minute

xxMikexx [17]

Let x = the minutes that Tom has remaining before exceeding 500 minutes.

Because he has already used 230 minutes, the total minutes he has is
x + 230
We want this total to be less than or equal to 500 minutes.
Therefore
x + 230 ≤ 500

Answer: x + 230 ≤ 500

Robert collected 330 aluminum cans. If 100 aluminum cans weigh 4 pounds, and the recycling center is paying 25 cents a pound, ho

labwork [276]

First, determine the weight of 330 cans with the given conditions,
(330 cans) x (4 lbs / 100 cans) = 13.2 lbs
Then, the price is determined by multiplying this weight to the price that the recycling center is paying,
(13.2 lbs) x (25 cents / lb) = 330 cents = $3.3
Thus, Robert will be paid $3.3.
