37 students get at most 67 scores.
The numbers 60-67 represent the lower quartile (lowest 25%). 25% of 60 is 15 not 30. Therefore it is incorrect.
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
-----> equation A
She sold 66 bottles more in the afternoon than in the morning
so
----> equation B
substitute equation B in equation A

solve for y

therefore
Ann sold 124 bottles of drinks in the morning
2) (-1,1), (2,-2), (4,-3)
1) (15+6-5x+4)
= 25-5x
= 5(5-x)
2) (24-10+8x+9)
= 23+8x
