In a class, every student knows French or German (or both).
15 students know French, and 17 students know German.

Given


Required
Determine and solve the inequality
The number of days is represented with D
So:
On any D number of days, the family would have covered a distance of 350 * D miles
If the total distance is at least 1400, then the inequality is:

[The term "At least" is used to represent <em>greater than or equal to</em>]

Divide through by 350



<em>This means that the family must travel for at least 4 days.</em>
