This looks like common core which is never straight forward.It seems as though they are asking for the perimeter and not area,since they used feet for the distance around instead of sq.ft.
Answer:
<em>$195</em>
Step-by-step explanation:
15a + 12c
5 adults and 10 children means a = 5 and c = 10
15a + 12c = 15(5) + 12(10) = 75 + 120 = 195
5.95 + 2.95 = 8.9
8.9 + 29.95 = 38.85
62.35 - 38.85 = 23.5
So Daniel spent $23.50 on long distance calling
You put 15 over 65 is equal to 50 over x, then you multiply diagonally so 15x = 3250 then you divide both sides by 15 to get 216.67 which means 50 pencils equals 2.17 dollars
