Help please,

Emily wants to go to Europe. Her plane ticket costs $510 and each day she will pay $120 for a hotel and $60 for food. Which of the following equations represents the number of d days she can go if she is williing to pay $2310 for the whole trip?

A. 510 + (120 + 60)d = 2310
B. 510 + 120 +60d = 2310
C. 510 + 120d + 60 = 2310
D. 510d + 120d + 60d = 2310

Answer 1

A should be your answer. since the number that will not change and that she only has to pay once is her plane ticket, that will not have a variable. but since she's paying for a hotel and food every day they have the variables cause their final costs depend on the number of days.

Answer 2

Choice A

Explanation:

120 for a hotel per day

60 for food per day

and initial cost for the ticket 510

120+60 a day + 510 rewritten as 510+(120+60)d=2310
