Answer:66.4
Step-by-step explanation:

$30 + $35 = $65
Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)
$65 + $3.90 = $68.90 ($65 + 6%)
OR
You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)
Answer:
111 is X
Step-by-step explanation:
So the theroum for any extended angle is to add the two opposite angles.
So if you add the 2 numbers is suppose to be X.
75+36=111
Thats it
Ok so
8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug
profit=R20m-8000
where m=number of mugs sold
(R20 means 20 rand)
f(m)=R20m-8000
$1 = 2 weeks
-
<u>Multiply by 800:</u>
$1 x 800 = 2 x 800 weeks
$800 = 1600 weeks
-
Answer: You need <u>1600 weeks </u>to get $800
