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
so
[tex]x+y=314[/tex] -----> equation A
She sold 66 bottles more in the afternoon than in the morning
so
[tex]x=y+66[/tex] ----> equation B
substitute equation B in equation A
[tex]y+66+y=314[/tex]
solve for y
[tex]2y=314-66\\2y=248\\y=124[/tex]
therefore
Ann sold 124 bottles of drinks in the morning
