The radical parts are gonna be easiest. You plug the radicals into your calculator and get a decimal. Next, you determine which decimal is greater. For turning fractions into decimals, change the fractions into improper fractions and divide the numerator by the denominator (the top number and the bottom number). You'll get a fraction then compare.
For the graphing area, you do the same thing, turn everything into decimals and place them on the graph.
Good luck!
Answer:
The profit for any purchased of bananas is R2.
Step-by-step explanation:
Cost of 1 kg banana = R 3
Banana purchased = 4 kg
So, the cost of 4 kg bananas = 4 x 3 = R 12
Amount paid = R 14
Profit = R 14 - R 12 = R 2
So, the profit on any purchased of bananas is R 2.
