Considering the definition of an inequality, the inequality that can be used to determine x is 20x + 10≤ 80
An inequality is the existing inequality between two algebraic expressions, connected through the signs:
An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
A rental car company charges $20 per day to rent a car and $0.10 for every mile driven.
Addison wants to rent a car, knowing that:
On the other hand, x represents the maximum number of days Alyssa can afford to rent for while staying within her budget.
Then, the inequality that can be used to determine x is:
20x + 0.1×100≤ 80
So:
20x + 10≤ 80
In summary, the inequality that can be used to determine x is 20x + 10≤ 80
