Step-by-step explanation:
Total amount of cookies = 4250
butter cookies, b
Almond cookies, a
Chocolate cookies, c
It made 715 more butter cookies than
almond cookies
b = a + 715
It made 5 times as many chocolate cookies as almond
5a = c
Total amount of cookies
= a + b + c
= a + (a+715) + (5a)
= 7a + 715
7a + 715 = 4250
7a = 4250-715
a = 3535 / 7
a = 505
c = 5a
= 5 (505)
= 2525
The factory make 2525 chocolate cookies.
Step-by-step explanation:
Judging from the high of 400, her day 21 appears to be approx 300
if she put in 100 then the next five days she added a total of 200 more to reach 300
200/5 = $40 / day
Answer:
[A] -3(2x-2.5)
Step-by-step explanation:
<em>Given:</em>
<em>Which expression is equivalent to -6x + 7.5?</em>
<em>Solution:
Going through all answer choices:</em>
<em>[A] -3(2x-2.5)</em>
<em>Simplify</em>
<em>-6x + 7.5</em>
<em />
<em>[B] -3(2x + 2.5)</em>
<em>Simplify</em>
<em>-6x - 7.5</em>
<em />
<em>[C] -3(2x-7.5)</em>
<em>Simplify</em>
<em>-6x+22.5</em>
<em />
<em>[D] -3(2x + 7.5)</em>
<em>Simplify</em>
<em>-6x - 22.5</em>
<em />
<em>Hence, the answer is [A] -3(2x-2.5)</em>

In this question, <span>q is the number of buggies the company can sell in a month if the price is $p per buggy. The revenue should be number of buggies sold(q) multiplied by the price(p). The equation would be:
revenue= p * q
revenue= p * (-4p + 616)= -4p^2 + 616p
The maximum revenue should be in the peak of the graph. The calculation would be:
</span>-4p^2 + 616p
-4*2 p^2-1 + 616*1 p^1-1=0
<span>-8p + 616=0
8p= 616
p=77
Put p=77 in the revenue equation would result
</span>revenue= -4p^2 + 616p
revenue= -4(77^2) + 616(77) = -23716 + 47432= $23716
Make them have common denominators: 14/8(3/3)=42/24, 15/12(2/2)=30/24, 42/24+30/24. Add numerators: 42+30=72, 72/24. Simplify: 72/24=3, 24/24=, 3/1=3. 3 is your answer :)
