The number of scented candles ... x
the number of unscented candles ... y
x + y = 28
$16 * x + $10 * y = $400 ... 16 * x + 10 * y = 400
If you would like to know how many scented and how many unscented candles did the shop sell today, you can calculate this using the following steps:
x + y = 28 ... x = 28 - y
16 * x + 10 * y = 400
____________________
16 * (28 - y) + 10 * y = 400
16 * 28 - 16 * y + 10 * y = 400
448 - 400 = 16 * y - 10 * y
48 = 6 * y /6
y = 48 / 6
y = 8
x = 28 - y = 28 - 8 = 20
Result: The candle shop sold 20 scented candles and 8 unscented candles today.
Answer:
one half of two fifths of x would be equivalent to one fifth of x
A perfect score on a test with 25 questions is 100.

=> 25 * 4 points = 100 points.
Fred got a score of 80 on the tes.
We need to write a division sentence usingnegative numbers where the quotient represents the number of questions Fred answered incorrectly
=> 100 - 80 = 20 points.
=> 20 / 4 points = 5 questions
