I use math all the time in the real world. Whenever I am cooking or baking, and need to make a small batch of somthing, I divide fractions to do it. Say the recipie calls for a cup of flour but I am making a half batch I divide it by 1/2 to cut it in half. Same with 1/2 cup of flour. I divide it by 1/4 to cut it in half.

Answer:

I went shopping once for ingredients of a cake, but i didn't know what my finale price would be. So i estimated what the total cost could be, then i took all the prices and added them up then divided the price by how many ingredients i got to find the average and it was pretty close to my estimate. So math can help when you go shopping. (Sorry if how i find my prices is weird, i kinda just stand in one spot for at least 5 - 8 mins trying to find my price)

lions [1.4K]

The second store offered the better buy at the price of $92.00.

What is better buy?

Better buy refers to the lowest price out of the prices offered by the three stores.

In order to determine the lowest price, the no discount price of the first store needs to be compared to the prices of two other stores, bearing that after-discount price is the pre-discount price multiplied by 1 minus the discount rate.

First store price=$95.00

Second store after-discount price=pre-tax discount price*(1-discount rate)

pre-discount price=$115

discount rate=20%

Second store after-discount price=$115*(1-20%)

Second store after-discount price=$92.00

Third store after-discount price=pre-tax discount price*(1-discount rate)

pre-discount price=$105

discount rate=10%

Third store after-discount price=$105*(1-10%)

Third store after-discount price=$94.50

W know the cost of each kind of meat

Chicken = 4 AED

Beef = 3 AED

We also know how much of each we will be buying

Chicken = 3.6 kg

Beef = 2.2 kg

Multiply each price of meat by its respective weight, then add the products together for you final answer.

4(3.6) + 3(2.2) = 21

What is y-intercept of the graph

Kipish [7]

Answer:

1a. y-intercept: 12

1b. slope: -3/2

1c. equation: y = -3/2x +12

2a. y-intercept: -9

2b. slope: 2

2c. equation: y = 2x -9

Step-by-step explanation:

A) We observe the pattern to be <em>x-values in the table increase by 2, while y-values in the table decrease by 3</em>. We notice the first x-value is 2, so extending the table upward to x=0 would tell us the y-intercept. That is, adding 3 to the first y-value will give the y-intercept as (x, y) = (0, 12).

B) We have already observed that the "rise" (change in y) is -3 for each "run" (change in x) of 2. The slope is the ratio of these changes:

slope = m = rise/run = -3/2

C) From the above, we know that m=-3/2 and b=12. Putting these values into the equation for the line gives ...

y = -3/2x +12

A) We observe the pattern to be <em>y-values increase by 2 while x-values increase by 1</em>. As before, we can find the point that would go before the first one shown in the table. It will have an x-value of 0 and a y-value of -9.

the y-intercept is -9

the slope is 2/1 = 2

the equation is y = 2x -9
