Answer:
well it uses the compound interest formula
F(x) = P_{0}(1 + \frac{r}{100})^x
so in your question
x = time in years for the initial formula
P_{0} = 293,.... r = 6% ...and...
then you need to substitute x = 4
simplify the brackets and you should get the answer.
4x+2y-6z-x-3y+2z= 3x-y-4z

Answer:
Donna swims 8 km each week.
Step-by-step explanation:
To be able to find the answer, you have to consider that 1 km is equal to 1000 meters and with this, you can use rule of three to find the kilometers in 8000 meters:
1 km → 1000 meters
x ← 8000 meters
x=(1*8000)/1000=8 km
According to this, the answer is that Donna swims 8 km each week.
