Answer:
Step-by-step explanation:
Interest formula -
I = P × R × T
I = 3,280 × 0.3% × 9
What I basically did there wws multiply the amount of money, the simple interest, and the time.
Turn 0.3% into a decimal by dividing by a 100 which should give you 0.003
I = 3,280 × 0.003 × 9
Put that into a calculator, you get $88.56
Now, that's just the interest amount. Now you add it back to 3,280 to get the *total* amount.
3,280 + 88.56 = 3,368.56
Cathy ends us paying $3,368.56
Hope what I said made sense.
For this case we propose a system of equations:
x: Variable that represents the amount of hours that Olivia's mother drove
y: Variable that represents the amount of hours that Olivia's father drove
So, we have:
From the first equation we have:
Substituting in the second equation:
Thus, Olivia's father drove 3 hours.
Olivia's mother drove 11 hours.
