The answer is the last choice, 8x.

The expression to represent the problem would be x+8; Where x is the unknown amount of orders received on Thursday, and 8 is the amount received on Friday.

Combined, the total would be 8x.

x+8=8x

Answer:

$5G + 4S + 2B = 26$

$2G + 2S + 2B = 13$

$3G + 4S + 6B = 26$

Step-by-step explanation:

Given

Represent Gold with G, Silver with S and Bronze with B

Required

Determine the system of equations

The packages are represented as:

The first: 5G + 4S + 2B

The second: 4G + 4S + 4B

The third: 3G + 4S + 6B

Each of the package costs $26.

So, we have:

$5G + 4S + 2B = 26$ -- (1)

$4G + 4S + 4B = 26$ -- (2)

$3G + 4S + 6B = 26$ -- (3)

Divide both sides of (2) by 2

$4G + 4S + 4B = 26$

$2G + 2S + 2B = 13$

So, the system of equations are:

$5G + 4S + 2B = 26$

$2G + 2S + 2B = 13$

$3G + 4S + 6B = 26$
