Answer: $15

Step-by-step explanation:

8 cookies cost $12 you divide 12 by 8 and then you get 1.5 which equals 1.50 so each cookie is 1.50. So for 10 cookies you multiply 10 times 1.50 and you get your answer $15. 10 cookies cost $15

PLEASE HELP!
Igoryamba
Hello! $200 is the fixed amount. B doesn't have 200 as part of the problem, so B is eliminated. A is also out, because you add, not subtract. 100 is the amount of boots made, not the amount made per pair of boots. 100 would be the value of "x". The cost per day is $9,200, and 9,200 - 200 is 9,000. With 100 pairs of boots being made each day, 9,000/100 is 90. It would cost $90 per pair of boots made, with the variable "x" being beside it. The correct equation would be C(x) = 90x + 200. The answer is D.

ANSWER
0.073 \% = 0.00073


EXPLANATION

Recall that,

\% =  \frac{1}{100}


That is why
100\%
is equivalent to
1.





This implies that,


0.073\% = 0.073 \times  \frac{1}{100}






This is the same as,


0.073\% = \frac{0.073}{100}


When we are dividing by
100
we move the decimal point backwards two times.


This implies that,

0.073\% = 0.00073
