Geri used coupons at the grocery store and received a discount of $40.94. Once her discount was subtracted, the final cost of her purchases was $122.80. What was the approximate percent decrease in the price of her groceries due to the coupons?
Step-by-step explanation:
Price after discount = 122.80
Discount = 40.94
So, amount before discount = 122.80 + 40.94 = 163.74
[tex]decrease[/tex] [tex]in[/tex] [tex]price[/tex] = [tex]\frac{discount}{original price}[/tex] x 10
= [tex]\frac{40.94}{163.74} (100)[/tex]
= 0.25
= 0.25 x 100
= 25%

You are selling tickets for a high school basketball game. Student tickets cost $3 and general admission tickets cost $5. You sell 350 tickets and collect $1450. How many of each type of ticket did you sell?
Answer:
5 stars? Answer down below
Step-by-step explanation:
a+b=350 => a=350 - b
3a + 5b = 1450
3(350-b)+b=1450
1050-3b+5b=1450
2b=400
b=200
a=150
There are 200 student ticket and 150 general admission ticket sold.
What is selling price?The selling price is used to sell the item at a certain cost and can be calculated using the selling price formula. The amount that the buyer pays to buy the product is called the selling price.
Here,
We sold some number, x, of $5 tickets and some number, y, of $3 tickets. If we sold 350 tickets total then x + y = 350. If we made $1450 total on ticket sales, then the sum of y tickets at $3 plus x tickets at $5 needs to equal $1450.
So,
$3y + $5x = $1450
and x + y = 350
Solve system of equations.
3(350-x) + 5x = 1450
1050 -3x + 5x = 1450
2x = 400
x=200
y + 200 = 350
y=150
Thus, there are 200 student ticket and 150 general admission ticket sold.

On a coordinate plane, the x-axis is labeled number of golf balls and the y-axis is labeled weight (in grams). A line goes through point (50, 9.9) and (300, 50).
ANSWER:
A
EXPLAIN:
Since all the six balls have same weight and the total weight is given as 273g, then weight of one ball will be
273/6=45.5 g
1 ball=45.5 g
2 balls =2*45.5=91 g
3 balls =3*45.5=136.5 g
4 balls=4*45.5=182 g
5 balls =5*45.5=227.5 g
6 balls =6*45.5=273 g

Answer:
It’s b.
Step-by-step explanation:
To get the slope of the line, you need to points. Two points you already have are (0,0) and (-5,6). So all you need to do is plug those points into slope equation (y1-y2 over x1-x2) 0-6 over 0+5 equals -6/5. The slope equals -6/5, and when you plug it into y=mx+b it equals y=-6/5x. Which is b.
