Answer:
r = c -km÷m
Step-by-step explanation:
C=( r+k) m (multiple the m with the letters in the brackets)
rm + km= c (cross the km over the equal sign and it will be a negative)
rm= c- km (then divide everything by my)
rm÷m = c - km÷ m
r = c- km÷ m
its 30 because if you add the numbers together then you get 90, then you do 180-90 and get 90, divide 90 by 3 and get 30
15% of R560 - 15% of R500
=> 0.15 × 560 – 0.15 × 500
=> 0.15 ( 560–500)
=> 0.15 × 60
=> Rs. 9
