Final answer:
Evelyn can afford to stay for a maximum of 4 days in the hotel, as determined by the budget inequality 420+140n≤ 1100, which upon solving for n gives us n≤ 4.857....
Step-by-step explanation:
Evelyn's vacation budget is constrained by the inequality 420+140n≤ 1100, where n represents the number of nights she can spend in the hotel. To determine the maximum number of days she can stay, we need to solve for n. This involves isolating n on one side of the inequality:
140n ≤ 1100 - 420
140n ≤ 680
n ≤ ⅔
Dividing both sides by 140, we get:
n ≤ 4.857...
Since Evelyn can't stay for a fraction of a day, we round down to the nearest whole number.
Thefinal answer is that Evelyn can stay for a maximum of 4 days in the hotel.
