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
D
A

Answer: y= 40x-10 , where = number of lawns.
Step-by-step explanation:
In linear equation y= mx+b with one variable x, m= slope , b= y-intercept.
[Slope rate of change of y with respect to x, y-intercept = initial value of y at x=0]
Given: Peter cuts lawns and makes $40 per lawn.
let x = number of lawns
i.e. slope = $40
He spends $10/day in work expenses.
i.e. y-intercept = -10 [for each day]
So equation becomes : y= 40x-10 , where = number of lawns.
