9514 1404 393

Step-by-step explanation:

Let d represent the number of dimes. Then 16-d is the number of nickels, and the total value is ...

  0.10d +0.05(16 -d) = 1.40

  0.05d + 0.80 = 1.40 . . . . . . . eliminate parentheses

  0.05d = 0.60 . . . . . . . . subtract 0.80

  d = 12 . . . . . . . .dimes

  (16 -d) = 4 . . . . nickels

Diane has 12 dimes and 4 nickels.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
