Let's answer this step-by-step.

First of all, let's estsblish the original price of the commodity as being 100%. Therefore:

Original price of commodity = 100%

Then, when A sold the commodity to B, it was sold at a 10% profit. Therefore:

Price of commidity when A sold to B:
100% x 1.1 = 110%

After that, when B sold it back to A, it was sold at a 10% loss. Therefore:

Price of commodity when B sold to A:
110% x 0.9 = 99%

Hence, A now has 99% of the original value of the commidity.

zimovet [89]

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

Step-by-step explanation:

Given,

Start up fee to receive internet = $30

Per month charges = $13

Total amount = $134

Let,

x be the number of months.

y be the total cost.

y = 13x+30

Putting y=134

$134=13x+30\\13x+30=134$

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.
