How would you write a real-world problem that models the following equation: 0.08x=0.06x+140?
The number of days that the temperature has been below zero is 40 fewer than the number of days the temperature has been above zero.
If Alex gained as much money as she lost, she would have 40 dollars.
Marsha is below sea level. To get as far above sea level as she is below, she would have to move to a location 40 feet higher.
The amount of money a stock lost in the stock market was $40 more than it gained.
A company bought a new machine for a total cost of $140. They decided to pay for it using two different interest rates. The initial cost, represented by 0.08x, was financed at an 8% interest rate, while the remaining amount, represented by 0.06x, was financed at a 6% interest rate. How much money did they initially borrow at each interest rate?
What is the answer? Chose one of the above
Let's choose the third real-world problem:
Marsha is below sea level. To get as far above sea level as she is below, she would have to move to a location 40 feet higher.
In this case, we can represent the equation as:
x + 40 = -x
Solving this equation, Marsha is currently 20 feet below sea level.
