Answer:

The cooperative has to make 70 shirts per day.

Step-by-step explanation:

Let x shirts be the number of shirts in a day  the cooperative has to make to fulfill his plan.

In 8 days, it will make 8x shirts.

Everyday, overfilling the norm by 10 shirts, the cooperative makes x + 10 shirts in a day.

The cooperative fulfilled his plan in 1 day less, so it spent 8-1=7 days and made 7(x+10) shirts.

The number of shirts is the same, so

8x=7(x+10)\\ \\8x=7x+70\\ \\8x-7x=70\\ \\x=70

The cooperative has to make 70 shirts per day.

Aleksandr-060686 [28]

Answer:  Second option.

Step-by-step explanation:

Let be "e" the number of easy puzzles Tina solved and "h"  the number of hard puzzles Tina solved.

Set up a system of equations:

\left \{ {{e+h=50} \atop {30e+60h=1,950 }} \right.

You can use the Eliminationn Method to solve this system of equations:

  • Multiply the first equation by -30.
  • Add the equations.
  • Solve for "h".

Therefore, through this proccedure, you get:

\left \{ {-30e-30h=-1,500} \atop {30e+60h=1,950 }} \right.\\.........................\\30h=450\\\\h=\frac{450}{30} \\\\h=15
