✠ Given data ✠
- Tamekia earns between $6.00 and $6.25 per hour.
- Marsha earns between $7.50 and $8.00 per hour.
✠ To find ✠ How much more money will Marsha earn than Tamekia if they each work 22 hours ?
✠ Step-by-step explanation ✠
- In one hour, Tamekia earns between $6.00 and $6.25.
- Then in 22 hours, she will earn between $(22 × 6.00) and $(22 × 6.25), i.e., between $132.00 and $137.50.
- In one hour, Marsha earns between $7.50 and $8.00.
- Then in 22 hours, she will earn between $(22 × 7.50) and $(22 × 8.00), i.e., between $165.00 and $176.00.
Clearly, Marsha will earn more than Tamekia.
- Here, $(165.00 - 132.00) = $33.00
- and $(176.00 - 137.50) = $38.50
✠ Answer ✠
Therefore, Marsha will earn about between $33.00 and $38.50 more than Tamekia if they each work for 22 hours.
