To compare unit prices, you first have to find the unit prices
for whistles, the unit prices are:
$21.25/25=0.85
36/50=0.72
60/80=0.75
difference between the highest unit price and the lowerest: $0.85-$0.72=$0.13
Kazos: 10/25=0.40
18.5/50=0.37
27.20/80=0.34
so the highest unit price is $0.40
I’m pretty sure that I’m pretty sure that question 2 is 1 minute and 40 seconds. And for number 3 I got B. 0.25 because if you look at where the line makes a direct cross between pounds and dollars that first one is 8 pounds for 2 dollars. If you divide 8 by 2 you will get 0.25. Hope this helped :)
Answer:
6 chickens, 11 cows.
Step-by-step explanation:
x - chickens
y - cows
x + y = 17
2x + 4y = 56 <-- chickens have 2 legs, cows have 4.
y = -x + 17
Substitute (-x+17) for y in the second equation.
2x + 4(-x + 17) = 56
2x -4x + 68 = 56
2x = 12
<u>x = 6 chickens</u>
Now substitute 6 for x
6 + y = 17
<u>y = 11 cows</u>

Step-by-step explanation:
To answer the question, you have to find out how much 49 sold cookies amounts to, so multiply 49 by however much it is per cookie.
Then, subtract the daily expense, $18, by the number you got from the total amount earned from the cookies sold, and that number would show the daily profit earned by selling 49 cookies.
Hope this helps :)
