Answer:
<h2>120 Pennies</h2>
Step-by-step explanation:
First, we need to find 80% of 400
400 x 0.8 = 320
Now 50% of 400 is 200
320 - 200 = 120

Hello !
You have to do as follow :

Answer: y= -3x + 4
Explanation: As the general equation of line is y= mx + c where m is the slope of the line and c is the y intercept.
=> for m we need to find the slope of line which is y2 - y1/ x2 - x1
=> 7-1/ -1-1 = 6/-2 = -3
and as we can in the diagram the y intercept is 4
that means our equation for the given line is y = -3x + 4.
It is an inverse relationship.
There is enough food for 156*125=19500 person-days.
If the food can last (125+70)=195 days, there are
19500 person-days / (195 days)
= 100 persons
