Andrea is at the grocery store buying fruit for a smoothie stand. She needs 7 boxes of raspberries for every 5 bunches of banana
Degger [83]

Answer:

The greatest number of bunches of bananas that Andrea can buy is 15 and the greatest number of boxes of raspberries that Andrea can buy is 21 to maintain the ratio 7:5

Step-by-step explanation:

Let

x ---->the greatest number of boxes of raspberries that Andrea can buy

y ---->the greatest number of bunches of bananas that Andrea can buy

we know that

100\%+8\%=106\%=108/100=1.08 ---> sales tax

\frac{x}{y} =\frac{7}{5}

x=\frac{7}{5}y ----> equation A

1.08[2.50x+3.00y]\leq 135 ----> inequality B

substitute equation A in the inequality B

1.08[2.50(\frac{7}{5}y)+3.00y]\leq 135

solve for y

Multiply by 5 both sides to remove the fraction

18.9y+16.2y\leq 675

35.1y\leq 675

y\leq 19.23

so

The maximum value of y is 19

Find the value of x

replace the value of y in equation A until you get an integer value that satisfies the ratio 7:5  

For y=19

x=\frac{7}{5}(19)

x=26.6

For y=18

x=\frac{7}{5}(18)

x=25.2

For y=17

x=\frac{7}{5}(17)

x=23.8

For y=16

x=\frac{7}{5}(16)

x=22.4

For y=15

x=\frac{7}{5}(15)

x=21

therefore

The greatest number of of bunches of bananas that Andrea can buy is 15 and the greatest number of boxes of raspberries that Andrea can buy is 21 to maintain the ratio 7:5

<u><em>Verify the inequality B</em></u>

1.08[2.50(21)+3.00(15)]\leq 135

1.08[52.5+45]\leq 135

105.3\leq 135 ----> is true

Can someone help me with this question me and my friends are fighting over it?
ki77a [65]
Okay so I am not 100% sure but I think it is C. 1/12;

Because if you rearrange all the letters so that W is is the beginning you get 6 different combinations.

Then I multiplied those 6 combinations by 4 because there are 4 letters.

Once I multiplied I got 2/24 because there are 24 possibilities in total, and we are looking for the probability of getting those 2 combinations.

I simplified 2/24 to its lowest form and I got 2/24 = 1/12.

So the correct answer is C.1/12, hope this helps!

HELP!
aev [14]

As you can see, in the table of the first function, f(2) = 18, and in the table of the second function g(2) = 18. Then, for x = 2, f(x) = g(x). and x =2 is the solution of the equation.

Answer: x = 2.
