Tina is saving to buy a notebook computer. She has two options. The first option is to $400 away initially and save $30 every mo
LuckyWell [14K]

Answer:

Let n represent the number of months after Tina would save the same amount using either option.

400 + 30n = 100 + 50n

400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality

400 = 100 + 20n            Combine like terms.

400 − 100=100 + 20n − 100 Subtraction Property of Equality

300 =20n

300

20

 =  

20n

20

15 months=n

After 15 months, Tina will save the same amount using either option.

400 + 30(15)=100 + 50(15)

400 + 450=100 + 750

850 = 850

After 15 months, Tina will save $850 with either option.

Maxim has been offered positions by two car companies. The first company pays a salary of $8000 plus a commission of $900 for ea
Kaylis [27]

Answer:

16 cars.

Step-by-step explanation:

Let x represent number of sold cars.

We have been that 1st company pays a salary of $8000 plus a commission of $900 for each car sold. We can represent this information in an expression as:

900x+8000

We are also told that second company pays a salary of $14400 plus a commission of $500 for each car sold. We can represent this information in an expression as:

500x+14,400

To find the number of cars sold, which will make the total pay the same, we will equate both expressions and solve for x as:

900x+8000=500x+14,400

900x-500x+8000=500x-500x+14,400

400x+8000-8000=14,400-8000

400x=6,400

\frac{400x}{400}=\frac{6,400}{400}

x=16

Therefore, 16 cars would need to be sold to make the total pay the same.
