Answer:

$6 = cost of small box

$8 = cost of large box

Step-by-step explanation:

Let s = cost of small box

     l  = cost of large box

(1)    12s + 3l = 96            (2)     6s + 6l = 84

    Multiply by -2                    <u> -24s - 6l = -192</u>

                                                -18s   = - 108

                                                     s = $6 = cost of small box

      12(6) + 3l = 96

         72 + 3l = 96

                 3l = 24

                   l = $8 = cost of large box

Artyom0805 [142]

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

\frac{15x}{15} = \frac{12 * 500}{15}  (* means multiplication if you do not know)

\frac{12 * 500}{15} = 100 × 4= 400 people
