Answer:
9 people
Step-by-step explanation:
40 + 18.25x = 124 + 7.75x
18.25x - 7.75x = 124 - 40
10.5x = 84
x = 84 ÷ 10.5
x = 8 people to EQUAL the same price as trampoline

Answer:
56x^2 + 11x - 12 = 0
Step-by-step explanation:
We can write it as follows
(x + 4/7)((x - 3/8) = 0
Multiplying each factor by the denominators of the fractions:-
(7x + 4)(8x - 3) = 0
Convert to standard form:-
56x^2 - 21x + 32x - 12 = 0
56x^2 + 11x - 12 = 0 (answer)
