To find this out we can set the expressions equal to each other:

Solve for 'x', first distribute:

Subtract 3 to both sides:

Subtract 2x to both sides:

So the answer is yes, after 3 weeks the dogs will be the same weight(because 'x' represents # of weeks).
So for the first one, you would have to multiply 2 six times. and then 2 with a -4 exponent is a little challenging. Okay, you would have to make it a fraction. so it would be 1/16. then you would just multiply 2 seven times.
<em><u>5</u></em><em><u>0</u></em><em><u> </u></em><em><u>per</u></em><em><u> </u></em><em><u>cent</u></em><em><u> </u></em><em><u>can</u></em><em><u> </u></em><em><u>also</u></em><em><u> </u></em><em><u>be</u></em><em><u> </u></em><em><u>termed</u></em><em><u> </u></em><em><u>as</u></em><em><u> </u></em><em><u>a</u></em><em><u> </u></em><em><u>half</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>number</u></em><em><u>.</u></em>

First youll need to add all the numbers together to get the cost of one tire
89.95 + 3.25 + 2.60 + 3.80 = $99.60
now that we know how much one tire costs, we can multiply the price of one tire by two to found out his final bill
99.60 x 2 = $199.20
Pete's final bill is $199.20
let me know if you have any other questions
