Answer:
$10t=m
Step-by-step explanation:
If for each hour is $10. 
She would earn the number of  hours times $10.
Example: She did babysitting for 4 hours this weekend. The equation is $10(4)=m or $10 x 4 = m.  m=40
 
        
             
        
        
        
The equation should look like :
[H+] = (1-a)(x) + (a)(y)
Where:
5.8 = -log [H+]
5.0 = -log x 
6.9 = -log y 
(1-a) = proportion of x
<span>a = proportion of y
so calculating a will give you the result of how many ounces are required</span>
