Answer:
they are 10 ppl in the crew
$12800×15/100=$1920
$10×100/80=$12.50
27 is how much kids did the survey because I added all the fractions together like how the question did 3/5 which is 3 × 5 = 15
Ab = (7x-6) → b = (7x-6)/a (1)
bc = (12-2x) → b = (12-2x)/c (2)
Since (1) = (2) → (7x-6)/a = (12-2x)/c OR a/c = (7x-6)/(12-2x) (3)
Multiply both numerators of (3) by the SQUARE of their respective denominators;
(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:
ac = (7x-6)(12x-2x) or ac = -14x² + 96x - 72
