The answer you are looking for is -2.

To solve the equation given, 7 ÷ 2 - 4.5 · 3 + 8, you follow the rules of PEMDAS.

First, solve 7 ÷ 2 to get 3.5. This leaves the equation to say "3.5 - 4.5 · 3 + 8".

Next, multiply 4.5 by 3 to get 13.5. The equation would now say "3.5 - 13.5 + 8".

Then, you subtract 13.5 from 3.5. 3.5 - 13.5 = -10. The equation says "-10 + 8"

Finally, add 8 to -10 to get a final answer of -2.

I hope this helps!

Toby's Tiny Toys have fixed expenses of $53,900 for the production of their tiny toys. Toby's has a variable expense of $12.50 a

ipn [44]

The total cost of the factory will be the sum of its variable costs and it's fixed costs. The factory has fixed costs of $53,900 and variable costs of $12.50 per unit produced. Let $x$ be the number of toy's produced by this Toby's Tiny Toys, then the total variable costs will be $12.50x$ . From this information we can gather that the cost function for this factory is,

$C(x)=53\,900+12.50x.$

On the other hand, if we let $x$ be the number of toys sold, we can gather that at the selling price of 16.50, the revenue function will be ,

$R(x)=16.50x.$

Toby's Tiny Toys will reach their break even point when the total costs are equal to the total revenue. At this break even point ,we have that

$R(x)=C(x)\\\implies 16.50x=12.50x+53\,900\\\implies 16.50x-12.50x=53\,900\\\implies 4x=53\,900\\\implies x=\frac{53\,900}{4} \\\implies x=134\,750.$

The company has to sell 134 750 units to break even.
