. Mr. Wayne has a 3-year contract for his cell phone service. He pays $124.65 each month to cover everyone in his family. How mu
telo118 [61]

Answer:

$4,523.40

Step-by-step explanation:

The cell phone cost is $124.65 per month. With 12 months in a year, we multiply $124.65 x 12 to get the answer $1,507.80. Since one year equals $1,507.80, we multiply this answer by 3 for 3 years to get $4,523.40. Thus three years of service with $124.65 a month would equal $4,523.40.

Mary drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 7 hours. When Mary drove h
ELEN [110]
There are two separate equations for this question that use the same variable.

Mary took 7 hours to complete a trip with traffic. This would use the following expression:

7x

Mary took 4 hours to complete the same trip without traffic. The average rate of speed was 27 mph faster than the trip with traffic. This uses the following expression:

4(x+27)

Both trips had the same distance. From the information provided, we can set up the following equation:

7x = 4(x+27)

x represents the average rate of speed on both trips.

Distribute 4 to each term in parentheses:

4 \times x = 4x
4 \times 27 = 108

7x = 4x + 108

Subtract 4x from both sides:

3x = 108

Divide both sides by 3 to get x by itself:

x = 36

The average speed for the slower trip is 36 mph.

We can plug this value into the first equation:

7(36) = 7 \times 36 = 252

Mary lives 252 miles away from the mountains.
