800-20 is 780. A third of 780 is 780(1/3) = 260. 780 - 260 = 520. 25% of $520 is 0.25(520) = 130. 520 - 130 = 390. One sixth of 390 is 390(1/6) = 65. 390 - 65 = 325. So, Bob kept $325 for himself.

Patio sets consisting of couches, umbrellas, and a firepit table are sold at a local furniture store, A set with 2 couches, an u

meriva

Answer:

$T = 600$

Step-by-step explanation:

Represent the table with T, couch with C an umbrella with U

We have the following:

$2C + U + T = 1875$

$C + T = 1075$

$2C + U = 1275$

Required

Determine the cost of a table

Make T $the\ subject\$ $in\ the$ first equation

$T = 1875 - (2C + U)$

In the third equation, we have that: $2C + U = 1275$

By substituting 1275 for 2C + U

$T = 1875 - (2C + U)$ becomes

$T = 1875 - 1275$

$T = 600$

<em>Hence, a table costs $600</em>
