Let
be the number of days spent at Tahoe and San Francisco, respectively.
We don't know the values of
and
yet, but we know that the holiday lasted 9 days:

We also know that each day spent in Tahoe costed 350 and each day spent in San Francisco costed 475. So, the total cost of the holiday is the sum of the number of days muliplied by their cost:

If we put the two equations together, we have the system

Which yields

We can make and use the equation: <em>A = 160( 1.03 )^y</em>: A = amount, 160 = amount put in, 1 + .03 = 1.03 = interest, and y as the number of years, as the money is compounded every year. (This is the compound interest equation, but I put in the numbers)
A) 160 * 1.03 = $164.80, 160 * 1.03² = $169.744 ≈ $169.74
B) 160 * 1.03⁵ = 185.48385 ≈ $185.48
The expression is the same as saying (((((160 * 1.03)1.03)1.03)1.03)1.03). This is like multiplying 160 * 1.03, which gives the amount for the first year. Then, that amount is multiplied by 1.03, which is the amount for the second year. This isi repeated until 5 years.
C) 160(1.03)³⁰
Answer:
-7 > v OR vice-versa [v < -7]
Step-by-step explanation:
Combine like-terms [-5v > 35], then divide by -5.
NOTE: Since you are dividing by a negative, reverse the sign.
