Applying proportions, it is found that the discounted price of each console at store B is given by:
B. $210.80.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
In this problem, at store B, 15 consoles sold for a total of $3,720, hence the price per console is of:
P = 3720/15 = $248.
A discount of 15% is applied, which means that the new price is 85% of the original price, hence:
P = 0.85 x 248 = $210.8.
Which means that option B is correct.

For each ounce of the product, let
x = ounces of moisturizing lotion used,
y = ounces of self-tanning lotion used.
The sum of the two lotions per ounce is equal to one ounce. Therefore
x + y = 1 (1)
Moisturizing lotion costs $0.70 per ounce.
Self-tanning lotion costs $22 per ounce.
Because the product costs $1.30 per ounce. Therefore
0.70x + 22y = 1.30 (2)
From (1), obtain
y = 1 - x (3)
Substitute (3) into (2).
0.70x + 22(1 - x) = 1.30
0.70x - 22x + 22 = 1.30
-21.3x = -20.7
x = 0.9718 ounces
From (3), obtain
y = 1 - 0.9718 = 0.0282 ounces.
A batch of the product is 700 ounces. Therefore the amount of self-tanning lotion used is
700*y = 700*0.0282 = 19.74 ounces
Answer: 19.74 ounces
