Consider the equation  $3a+0.1n=123$  


. If we solve this equation for n, which equation would result? 

•  $0.1n=123-3a$  

•  $n=123-3a-0.1$  

•  $n=1,230-30a$  

•  $\frac{3a-123}{0.1}=n$

Diego is buying shrimp and rice to make dinner. Shrimp costs $6.20 per pound and rice costs $1.25 per pound. Diego spent $10.55 buying shrimp and rice. The relationship between pounds of shrimp s, pounds of rice r, and the total cost is represented by the equation  $6.20s+1.25r=10.55$ 

What equation that makes it easy to find the number of pounds of rice if we know the number of pounds of shrimp purchased?

•  $r=\frac{\left(10.55-6.20s\right)}{1.25}$  

•  $r=10.55-6.20s$  

•  $s=\frac{\left(10.55-1.25r\right)}{6.20}$  

•  $r=s=10.55$
