Question

Should Jenna buy the smart phone at the top quality or big value? please use mathematical evidence. Assume that getting the lowest price is Jenna's only consideration

Answer 1

EXPLANATION

Let's consider the facts:

Discount price= 15% = 0.15 (in decimal form)

t=list price

A.

If there is a 15% price discount, so the table is selling at 100-15=85%

Then, the first equation representing the discount price is:

$\frac{85\cdot t}{100}$

Now, as the discount on the table is 15%, the selling cost of the table would be:

Second equation -->

$t-\lbrack\frac{15\cdot t}{100}\rbrack$

B.

1-->For first equation, the cost of the table after giving the discount has been calculated.

2--> For the second equation, the list price minus the discount amount is calculated.

C. Jenna sees a smartphone on sale for 1/4 off its list price.

Price of the smartphone at Top Quality =1/4 * list price

Price of the smartphone at Big Value= 75%=3/4 * list price

Jenna should buy the smartphone from Top Quality as it is at a lesser price.
