Ответ:
7 jarras costarán 14 $
Step-by-step explanation:
Si 3 cubiertos cuestan 7.20 $
1 cubierto cuesta 7.20/3 = 2.40 $
y 5 cubiertos cuestan 5* 2.40 = 12 $
que también cuestan 6 jarras = 12 $
Luego 1 jarra cuesta 12/6 = 2 $
Por lo que 7 jarras costarán: 7 * 2 = 14 $

Paralelogram's area:
A = 10×3.5 = 35 in²
Square's area:
A = 4² = 16 in²
Rectangle's area:
A = 12.5 × 6 = 75 in²
Total area:
75 + 16 + 35 = 126 in²
