We know that: 52 + 24 = 76.
You can also express it this way:
52 + 24 = 50 + 2 + 20 + 4 = ( 50 + 20 ) + ( 2 + 4 ) = 70 + 6 = 76
Or ( since 4 * 13 = 52 and 4 * 6 = 24 ):
52 + 24 = 4 * 13 + 4 * 6 = 4 * ( 13 + 6 ) = 4 * 19 = 76.

erma4kov [3.2K]

Answer:

$\boxed{195}$

Step-by-step explanation:

The fruit flies grows geometrically.

$125=80k^2$

Find the value of k.

$\sqrt{\frac{125}{80} } =k$

$1.25=k$

$P=80(1.25)^t$

$t$ is number of days.

$P=80(1.25)^4$

$P=195$
