In a hockey arena, a seat at rink level costs three times as much as a seat in the upper level. If five seats at rink level cost $112 more than eight seats in the upper level, find the cost of a seat at rink level. Please use system of linear equations by elimination OR substitution. I also need the work please.

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
