You buy an item for $100 with 15% added tax. So we find 15% of 100:
100 • 0.15 = 15
(A quick math here, and percentage of 100 will always be the same number of the percentage, for example 32% of 100 will be 32.)
100 + 15 = 115
a) the true sale price of the item is $115 (with tax included)
b) you are buying a $15 tax (for the item)
(I hope these are correct, the questions are really vague)
Answer:
Step-by-step explanation:
A jewellery shop sells 240 necklaces a month.
180 of the necklaces were sold via the shops website the rest were sold in a high street shop. This means that the amount that were sold in the shop would be the total amount sold for the month minus the amount that were sold via the shop's website. It becomes
240 - 180 = 60
The ratio of online sales to shop sales would be the number of necklaces sold online / the number of necklaces sold in the shop. It becomes
180/ 60 = 3/1 = 3
Answer:
The slope is $0.35/min and it gives the cost per minute of the phone used.
Step-by-step explanation:
We can model this situation with a linear equation of the form
where 
is monthly cost, 
is the number of minutes, 
is the flat monthly fee, and 
is the slope of the equation, or in our case, the amount of money charged per minute.
The slope is
,
in other words, the phone company charges $0.5 per minute.
With the slope in hand, the linear equation becomes
,
and we can find the monthly fee from that fact that for 300 minutes the cost is $131:
.
Therefore,
where the slope if the equation give the cost per minute of the phone used.
