Answer:
The capacity is 18 transistors, 43 resistors and 4 computer chips.
Step-by-step explanation:
This problem can be solved by a system of equations.
I am going to say that:
x is the number of transistors that are made.
y is the number of resistors that are made.
z is the number of computer chips that are made.
Building the system:
A transistor requires 1 unit of copper. A resistor requires 2 units of copper. There are 104 units of copper. So
A transistor requires 2 units of zinc. A resistor requires 3 units of zinc. A chip requires 1 unit of zing. There are 169 units of zinc. So .
A transistor requires 3 units of glass. A chip requires 5 units of glass. There are 74 units of glass. So
We have the following system:
The solution is:
The capacity is 18 transistors, 43 resistors and 4 computer chips.
Answer: We need to support her work for at least 15 days.
Step-by-step explanation:
Juana's mother receives a daily payment of 30 soles .
She has already 120 soles.
Let x = Number of days to save at least 550 soles.
Then, Total she has after x days = 120+30x
According to the question, we have
i.e. minimum value for x=15
Hence, we need to support her work for at least 15 days.
