Answer:

$51

Step-by-step explanation:

Let:

P= buckets of popcorn

S= soft drinks

First equation:

3p+7s=$52.50

Second Equation:

4p+1s=$20

Next:

multiply the first equation by 4 and the second by -3

First equation:

12p+28s=210

Second Equation:

-12p-3s=-60

Then:

25s=150

Then:

Divide each side by 25

S= $6 per soft drinks

Then:

4p+1(6)=20

Next:

subtract 6 from 6 and then subtract 6 from 20

Then:

4p=14

Then:

divide 4 from both sides

P= $3.50 per bucket of popcorn

Then:

6(3.50)+5(6)=$51
