Jane worked a 40 hour week at $5.50 an hour.
Joan earned $6.50 for 35 hours. What are their wages?
The problem asks for wages and specifies two rates($5.50 and $6.50 an hour)
and two times (40 and 35 hours, respectively), so the formula
rate x time = wage
from the formula list is appropriate.
Organize the facts into chart(table)
All that is necessary to solve this equation is to switch the sides of the equation.
Step 1: Write the equation from the chart.
rate X time = wage
Step 2: Solve the equation symbolically.
wage = rate X time
