2) Lisa is ordering sand from the Internet, On one site she found sand on sale for

Anastasy [175]

For this case we must find the unit cost (dollars per pound) of each site and then compare.

We take into account that:

1kg equals 2.205 pounds

So, we have:

Site 1:

$C = 2.25 \frac {dollars} {pound}$

Site 2:

$5kg = 5 (2.205\ pounds) = 11.025 pounds$

So, the unit cost is:

$C = \frac {14} {11.025} \frac {dollars} {pound} = 1.27 \frac {dollars} {pound}$

Thus, the best deal is on site 2.

ANswer:

The best deal is on site 2.

Which of the following expressions is this one equivalent to?

padilas [110]

Hello from MrBillDoesMath!

Answer:

Choice D, x-2

Discussion:

Observe the the highest order term in the numerator is x^4 and the highest order term in the denominator is x^3. So the highest order term in their quotient is x^4/x^3 = x. Choice D is the only possible answer as all other choices start with x^2
