Suppose the movie theater you work at sells popcorn I'm three different sizes. A small cost $2, a medium cost $5, and a large co

VMariaS [17]

Let, number of small, medium and large popcorn sold are s, m and l respectively.

So, s + m + l = 250 ....1)

Also, l = 2s ....2)

Total sum = $1726 = 2s + 5m + 10l .....3)

Putting value of l from 2) to 1) is :

s + m + 2s = 250

m + 3s = 250

m = 250 - 3s ....4)

Putting value of m and l in terms of s in equation 3)

We get :

2s + 5( 250 - 3s ) + 20s = 1726

7s = 1726 - 1250

s = 68

l = 136

m = 250 -3(68) = 46

Now,

$P_s=68\times 2 = \$136\\\\P_m = 46\times 5 = \$230\\\\P_l = 136\times 10 = \$1360$

Hence, this is the required solution.
