+118724 a television company charges $36 per month and increases it by 15% what is the rate now?
You need to know this $$15\% =\frac{15}{100}=0.15$$
Now there are 2 ways.
15% of 36 = 0.15*36 = $5.40 This is the increase.
New rate = $36+$5.40 = $41.40
------------------------------
The other way is for you to recognise that the original cost is 100% if it is increased by 15% then the new percentage will be 115% = 1.15
115% of $36 = 1.15*36 = $41.40
The second way is quicker but some people find it harder to understand.
