C = 24 ,5 ×50+49×24,5+24,5
\(C=24,5.\left(50+49+1\right)\)
\(C=24,5.100\)
\(C=2450\)
Ta có :
C = 24,5 x 50 + 49 x 24,5 + 24,5
= 24,5 x (50 + 49 + 1)
= 24,5 x 100
= 2450
Vậy C = 2450

C = 24 ,5 x 50 + 49 x 24 ,5 + 24 ,5
C = 24 ,5 x ( 50 + 49 + 1 )
C = 24 ,5 x 100
C = 2450
\(24,5\times50+49\times24,5+24,5\)
\(=24,5\times50+49\times24,5+24,5\times1\)
\(=24,5\times\left(50+49+1\right)\)
\(=24,5\times100\)
\(=2450\)
