Rita's company reimburses her expenses on food, lodging, and conveyance during business trips. The company pays $55 a day for fo
MArishka [77]
<span>"The company pays $55 a day for food and lodging and $0.45 for each mile traveled" means that if she travels m miles and is on a trip for x days then Rita will receive:

55x + 0.45m dollars. 


Rita drove 300 miles, means that m=300. Thus </span>55x + 0.45m becomes <span>

</span>55x+0.45m=55x+0.45 \cdot 300=55x+135 (dollars.)

She was reimbursed  $2,335 means that 55x+135=2,335.


Part A: 55x+135=2,335.

Part B: 

We are given the equation 55x+135=2,335. Subtracting 135 from both sides we have:

55x=2,335-135=2,200.

Dividing both sides by 55, we get: x=2,200/55=40.


Part C: since x represents the number of days Rita spend on this trip, and x=40, then Rita spent 40 days on this trip.

In this equation, the "-0.03" is the decay factor or "k"
We can now solve for half-life by this equation:
