Answer:
R 42.26
Step-by-step explanation:
To calculate the bill correctly we must add the orders separately and in the sweet cost when adding, we should write it as 0.59 not 59.
my order my friend's order
20.50 10.29
+ 10.29 + 0.59
<u> </u> 0.59
R 30.79 <u> </u>
R 11.47
<em>R 30.79 + R 11.47 = </em><em>R 42.26</em>
