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.

Write an equation that makes it easy to find the number

of pounds of rice if we know the number of pounds of

shrimp purchased.
