200 + 10x = 120 + 15x now solve the equation to find x, the number of hours that both companies will charge the same ammount

torisob [31]

Answer:

Step-by-step explanation:

Given the equation, $200 + 10x = 120 + 15x$ , let's solve for x as follows,

Subtract 200 from both sides

$200 + 10x - 200 = 120 + 15x - 200$

$10x = - 80 + 15x$

Subtract 15x from both sides

$10x - 15x = - 80 + 15x - 15x$

$-5x = - 80$

Divide both sides by -5

$\frac{-5x}{-5} = \frac{-80}{5}$

$x = 16$

Answer:

3 for $8

Step-by-step explanation:

Firstly, 3 for $8 is much better than 5 for $8. Same for 12 for $24 being better than 14 for $24, because it's the same price for a different amount. Now we multiply 3 for $8 by 3, to get 9 for $24, which is better than 12 for $24, so the answer is 3 for $8
