7) solve the problem: when making a long
distance call from a certain pay phone, the
first three minutes of a call cost $2.00. after
that, each additional minute or portion of a
minute of that call costs $0.50.0 use an
inequality to find the maximum number of
minutes one can call long distance for
$10.00

19 minutes

Step-by-step explanation:

Let x be the number of minutes the call lasts.

The first three minutes of a call cost $2.00.

Then minutes left.

Each additional minute or portion of a minute of that call costs $0.50, so minutes cost

The total cost is

The price of the call is $10.00, so the maximum number of minutes one can call long distance for $10.00 can be calculated from the inequality

When x=19, the cost of the call is $10.00. When x<19, then the price of the call is less than $10.00.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
