i am confusd as to how they came up with this answer can sumbody help me understand why the answer turned out to be the one it it.
Problem - Proportions:
At the market, a man buys six avocados for $13.35. All produce is 30% off today only. How much will two avocados cost you tomorrow at full price?
A) $4.00
B) $4.50
C) $5.00
D) $5.50
E) $6.00
You want to find the regular price per avocado because the question is asking you to calculate the cost of two of them.
You can find this by figuring out the sale price. The man paid $13.35 for 6 avocados. So divide the total cost by the number of avocados to get the price for one avocado.
13.35/6 = 2.225 this is the discounted price per avocado.
The discount is 30% less than the regular price.
If you take away 30%, you have 70% (since 100% - 30% = 70%)
So you know that $2.225 is 70% of the full price.
Full $ x 0.70 = 2.225
(Remember that if A x B = C, then A = C /B)
So full $ = 2.225 / 0.70 which, when we work it out either with the calculator or by hand, gives us = $ 2.50
At $2.50 per avocado, buying two would cost us $5.00, which is Answer C.
