Answer
Explanation:
Step1: Find Tyler's hourly - rate
The slope of Tyler's graph represents his hourly rate. Since the slope of Tyler's graph is 9, Tyler earns $9 per hour.
Step2: Find Miranda's hourly - rate
Use the formula for the rate of change (unit rate) $r=\frac{\text{Change in Earnings}}{\text{Change in Time}}$. For Miranda, when the time changes from 4 hours to 5 hours (a change of $\Delta t = 5 - 4=1$ hour), the earnings change from $44.80 to $56.00 (a change of $\Delta E=56.00 - 44.80 = 11.20$). So Miranda's hourly rate $r=\frac{56.00 - 44.80}{5 - 4}=\frac{11.20}{1}=11.20$ dollars per hour.
Step3: Find the difference in their hourly rates
Subtract Tyler's hourly rate from Miranda's hourly rate: $11.20−9 = 2.20$.
Answer:
Miranda earns $2.20 more per hour than Tyler.
