Answer:
food purchased= $9,600
Step-by-step explanation:
Giving the following information: 
Chivis Mexican restaurant pledges 12% of any food purchased
Minimum donation= $1,152
<u>To calculate the food to be purchased, we need to use the following formula:</u>
Donation= food purchased*0.12
1,152= food purchased*0.12
1,152/0.12= food purchased
food purchased= $9,600
 
        
             
        
        
        
First let's define variables:
 r: reading
 s: skimming
 We write the system of equations that adapts to the problem:
 r + s = 275
 (15/10) r + (10/15) s = 355
 We solve the system of equations:
 r = 206
 s = 69
 Note: see attached image for system solution.

Answer:
60
Step-by-step explanation:
K is the constant of proportionality or unit rate
(x, y)
(0, 0)
(2, 120)
(3, 180)
(4, 240)
120/2=60
180/2=60
240/2=60
The constant of proportionality or unit rate is 60
