Jenny wants to rent a truck for one day. She contacted two companies. Laguana's Truck Rentals charges $20 plus $2 per mile. Salv
Anna71 [15]

Answer:

20 miles.

Step-by-step explanation:

Let m be number of miles.

Laguana's Truck Rentals charges $20 plus $2 per mile.

Total cost of Laguana's Truck = 20+2m         .... (1)

Salvatori's truck rentals charges $3 per mile.  

Total cost of Salvatori's truck = 3m          ... (2)

We need to find the number of hours after that the total cost for both companies will be the same.

3m=20+2m

3m-2m=20

m=20

Therefore, after 20 miles the total cost for both companies will be the same.

Sam needs a web designer. Designer A is offering her services for an initial $450 in addition to $105 per hour. Designer B is of
gogolik [260]

Answer:

After 5 hours the two would charge the same amount of money.

Step-by-step explanation:

Designer A:  $450 + ($105/hr)x, where x is the number of hours worked;

Designer B:  $725 + ($50/hr)x

Equating these two formulas, we get:

$450 + ($105/hr)x = $725 + ($50/hr)x

Subtracting $450 from both sides:  ($55/hr)x = $275

Dividing both sides by $55 yields the number of hours worked:

x = $275/$55 = 5

After 5 hours the two would charge the same amount of money.
