By using the 20 percent off coupon that she found in the newspaper, Jill saved $4 on the extra large bag of dog food that she bought. what was the cost of the dog food without the coupon?

Answers

Answer 1
Answer:

The cost of the dog food without the coupon is $20.

What is the percentage?

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %.

It is given that 4 dollars are 20% of the original price of the dog food. Let's have x be the original price of the dog food.

The cost of the dog food without the coupon is calculated as:-

4=x ( 20 )

To get x alone divide both sides by 20 and solve further.

( 4 / 20 )= ( x ( 20) / 20 )

Solve the above equation by cancelling 20 to get the value of x.

4/20=x

Divide 4 by 20 to get the answer and multiply by the value 100 to get the actual cost of the product.

x = 0.2 x 100 = 20

Therefore, the cost of the dog food without the coupon is $20.

lalo has 1500 minutes per month on his cell phone plan. how many more minutes can he use if he has already talked for 785 minutes?

Answers

Answer:

Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.

Step-by-step explanation:

Total number of minutes per month lalo has on his cell phone plan = 1500

Number of minutes he has already talked in that month = 785

Number of minutes available to talk = total number of minutes he has - total number of minutes he has already used.

                                                           = 1500 - 785

                                                            = 715 minutes.

Thus, Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.



All you have to do is subtract 1500-785 in order to find the number of minutes left for him.
1500-785=715 more minutes left

How many points of intersection are on the graph of the following system?lbrace y = x2 + 3x − 7
y − x = 9


The linear-quadratic system has
(select)
points of intersection.

Answers

Answer:

2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)

Step-by-step explanation:

y − x = 9

y = x + 9

x+9 = x²+3x-7

x²+2x-16=0

x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17

x = 3.12 or x = -5.12

y = 12.12 or y = -3.87

billy and Ryan had a competition at the batting cage. billy hit 7 balls for every 4 balls Ryan hit. billy and Ryan hit a total of 99 balls. how many balls did each boy hit?

Answers

We are to find the number of hits Billy and Ryan had in this game. We are then to find 2 thing or in other words there are 2 variables that we have to solve. As a rule we need to find 2 relationships. The 2 relationships or equations are: 

B + R = 99

(B)/(R) = (7)/(4) or 4B - 7R = 0 
where B- Billy's hit and R - Ryan's hit. 

B= 63
R=36
