Answer:
Total cost of the trip = 243 + 72x
Step-by-step explanation:
Cost of airfare = $243
Amount spent per day = $72
Which expression can he use to help him find the cost of the trip?
Let
x = number of days spent in Alaska
Total cost of the trip = Cost of airfare + (Amount spent per day * number of days spent in Alaska)
= 243 + (72 * x)
= 243 + 72x
Total cost of the trip = 243 + 72x
If he spent 4 days on the trip
Total cost of the trip = 243 + 72x
= 243 + 72(4)
= 243 + 288
= $531
Since the skier has to rent skis for 30 dollars per day with
both passes, we can ignore it while solving the question.
A season pass is 350, while a daily pass is 75.

So a seasonal pass is equivalent to having 4.6667 daily passes. And you can't buy 0.6667 of a pass.
So, if you went at least 5 days with a seasonal pass, then the seasonal pass would be less expensive than a daily pass.
X=5/2
4x7.5=12x
30=12x
X=30/12
X=5/2
Let c be the ounces of clay that Elisa used. For small vases, the value of c should be less than or equal to 4.5 which can mathematically be expressed as c ≤ 4.5. For large vases, the value of c should be greater than or equal to 12, c ≥ 12. Thus, the answer to this item is letter D.
Use distributive property.
5 x 8x =40x
5 x 3y =15y
5 x -4 =-20
so your answer would be 40x+15y-20
Hope this helps!
