31.35d + 0.15(275) </= 280
Step-by-step explanation:
(Daily cost x number of days) + (mileage cost x number of miles) is less than or equal to $280.
If they ask you to solve it next:
31.35d + 0.15(275) </= 280
31.35d + 41.25 </= 280
31.35d </= 238.75
d </= 7.615629998
Round it down to 7 full days
Answer:
7c^2d-7c+4d-10
Step-by-step explanation:
Start off with the term that has c^2 in it. 5c^2d + 2C = 7c^2d, then since you have multiple choice, the d value differs between the two answer choices that have 7c^2d so you can do +3d +d to get +4d to get the fourth answer choice.
To check your work, you can add/subtract each term to see if you get 7c^2d-7c+4d-10
