At a carnival, Ann sold 314 bottles of drinks a day. She sold 66 bottles more in the afternoon then in the morning. How many bot

Paladinen [302]

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

Peter cuts lawns and makes $40 per lawn. He spends $10/day in work expenses. Write an equation in the form y = mx + b to represe

stepan [7]

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.
