Answer:

Ann sold 124 bottles of drinks in the morning

Step-by-step explanation:

Let

x ---> bottles sold in the afternoon

y ---> bottles sold in the morning

we know that

Ann sold 314 bottles of drinks a day

$x+y=314$ -----> equation A

She sold 66 bottles more in the afternoon than in the morning

$x=y+66$ ----> equation B

substitute equation B in equation A

$y+66+y=314$

solve for y

$2y=314-66\\2y=248\\y=124$

therefore

Ann sold 124 bottles of drinks in the morning

Answer:

-18.703

Step-by-step explanation:

a₁=-28(-1/2)¹⁻¹

r=-1/2

a₁=-28

r=-1/2

S₉=a₁ $\frac{1-r^{9} }{1-r}$

S₉=-28 $\frac{1-(\frac{1}{2})^{9} }{1-(\frac{1}{2}) }$

S₉= $-\frac{1197}{64}$

S₉=-18 $\frac{45}{64}$ S₉=-18.703125
