A company making backpacks charges $29.99 for each backpack. It costs $6.45 to make each backpack. The company can make backpack

Ne4ueva [31]

A minimum of 220 backpacks must be produced to obtain the desired benefits.

Since a company making backpacks charges $ 29.99 for each backpack, and it costs $ 6.45 to make each backpack, and the company can make backpacks in multiples of 10 and there is $ 1,000 in fixed costs, and the company wants to make at least $ 4,000 profit each week, to determine how many backpacks should be produced, the following calculation must be performed:

29.99 - 6.45 = 23.54
500 x 23.54 - 1000 = 10,770
250 x 23.54 - 1000 = 4.885
220 x 23.54 - 1000 = 4,178.80
210 x 23.54 - 1000 = 3,943.40

Therefore, a minimum of 220 backpacks must be produced to obtain the desired benefits.

Can you help me answer this question

r-ruslan [8.4K]

Division of a fraction is the equivalent of multiplying by its reciprocal
ex.
$\frac{\frac{A}{B} }{\frac{C}{D}}=\frac{A}{B} *\frac{D}{C}$
i suggest you try to remember this concept

in terms of your question

$\frac{\frac{4c-12}{4c+8}}{\frac{c-3}{c^2-4}}= \frac{4c-12}{4c+8} *\frac{c^2 -4}{c-3}$

from this point, just multiple the numerators together and denominators together, then simplify if necessary

fyi- difference of squares
$x^2-b^2 = (x-b)(x+b)$
relating that to
$c^2-4 = c^2 -2^2 = (c-2)(c+2)$

also a side note, you might want to factor out the 4 first in the top fraction
