Question

the formula w = 0.43g² - 0.06g + 9.1 models the average weight, w, in ounces, for a mouse who is fed g grams per day of a special food. according to the formula, how much will a mouse weigh when it is fed 13 grams of the special food per day? if necessary, round answers to the nearest hundredth.
a. 68.77 oz
b. 13.91 oz
c. 80.99 oz
d. 190.19 oz

Explanation:

Step1: Identify the formula and value of g

The formula is $W = 0.43g^{2}-0.06g + 9.1$, and $g = 13$.

Step2: Substitute g into the formula

$W=0.43\times(13)^{2}-0.06\times13 + 9.1$.
First, calculate $(13)^{2}=169$. Then $0.43\times169 = 72.67$, and $0.06\times13=0.78$.
So $W = 72.67-0.78 + 9.1$.

Step3: Perform arithmetic operations

$72.67-0.78=71.89$, and $71.89 + 9.1=80.99$.

Answer:

C. 80.99 oz
