Teboho has to sell a certain number of cars each month. For every car he sells over and above this number he earns 17% commissio
Nastasia [14]

The commission earned are R41123.17, R47931.67 and R15024.09

<h3>The prices of the cars before VAT was added</h3>

The VAT included prices are given as:

R271 800,00; R316 800,00 and R99 300,00.

The VAT rate is 12.36%.

So, the price before VAT is calculated as:

VAT included = Price without VAT * (1 + 12.36%)

This gives

VAT included = Price without VAT * 1.1236

So, we have:

Price without VAT = VAT included/1.1236

For the three cars, we have:

Price without VAT = R271 800.00/1.1236 = R241901

Price without VAT = R316800.00 /1.1236 = R281951

Price without VAT = R99300.00/1.1236 = R88377

Hence, the prices of the cars before VAT was added are R241901, R281951 and R88377

<h3>The commission he earned on the cars.​</h3>

This is calculated as:

Commission = Price * 17%

So, we have:

Commission = R241901 * 17% = R41123.17

Commission = R281951 * 17% = R47931.67

Commission = R88377 * 17% = R15024.09

Hence, the commission earned are R41123.17, R47931.67 and R15024.09

At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two
Svetlanka [38]

<u><em>Answer:</em></u> <em><u>290 calories in a cheeseburger and 230 calories in fries.</u></em>

<em><u>x = calories in a cheeseburger</u></em>

<em><u>y =  calories in an order of small fries</u></em>

<em><u>Four cheeseburgers and five small fries have 2,310 calories. Therefore</u></em>

<em><u>4x + 5y = 2310       (1)</u></em>

<em><u>Three cheeseburgers and two small fries have 1,330 calories. Therefore</u></em>

<em><u>3x + 2y = 1330        (2)</u></em>

<em><u>Equations (1) and (2) model the given situation.</u></em>

<em><u>To solve, multiply (1) by 2, and multiply (2) by 5 to obtain</u></em>

<em><u>  8x + 10y = 4620          (3)</u></em>

<em><u>15x + 10y = 6650          (4)</u></em>

<em><u>Subtract (3) from (4).</u></em>

<em><u>7x = 2030</u></em>

<em><u>x = 290</u></em>

<em><u>From (1), obtain</u></em>

<em><u>5y = 2310 - 4*290 = 1150</u></em>

<em><u>y = 230</u></em>

<em><u> x = 290, y = 23</u></em>

<u><em>Hope this helps!</em></u>
