Amari can spend at most $40 at the fair. It cost her $12 to enter the fair and $3 per ticket, t, to ride the rides.

i have no idea if you're looking for how many rides she can go on or the equation so i'll give you both lol.

Step-by-step explanation:

3t + 12 = 40

t represents the number of tickets (rides)

$12 is the entry fee.

$3 is the cost per ticket

to solve, use the subtraction property of equality. (subtract 12 from both sides)

3t + 12 - 12 = 40 - 12

3t = 28

divide each side by 3.

3t/3 = 28/3

28/3 = 9.3333...

amari can go on a maximum of 9 rides ($27) and stay within her budget of $40 or less.

$27 + $12 = $39.

she will have $1 left over.

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
