Answer:
0.09
Step-by-step explanation:
avg rate of change is: change in y/ change in x
so it´d be 3.59 - 0.89 / 2014 - 1984
= 2.7/ 30
= 0.09
note:
The slope formula and the average rate of change formula are the same, just written a bit different, so you could also use:
y2 - y1 / x2 - x1
P = 2L + 2w
Subtract 2L
from each side: P - 2L = 2w
Divide each side
by 2 : (P - 2L) / 2 = w
You could also write it as (P/2 - L) = w
Both answers are the same.
Answer:
$3780
Step-by-step explanation:
Salary per month = $10500
Expense on food
= 36% of the monthly salary
= 36% of $10500
= (36/100) × $10500
= 36 × $105
= $3780
So, they spend $3780 on food per month.
