I am assuming the problem is asking you to find an equation repersenting the situation.
In this case, realize that 150 will be a constant, and 60 will be attached to the variable, since the price of the textbooks changes based on how many textbooks there are.
Thus, the equation is:
Our answer is 60x + 150 = y.
Answer:
(4, - 2 )
Step-by-step explanation:
Given the 2 equations
x = 4 → (1)
- y = x → (2)
Substitute x = 4 into (2)
- y = × 4 = 2 ( multiply both sides by - 1 )
y = - 2
Solution = (4, - 2 )
Answer:
The interest rate was of 0.1173 = 11.73%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this problem, we have that:
So
So
The interest rate was of 0.1173 = 11.73%.
