Answer:

Step-by-step explanation:

I started your problem by simply adding all of the hours up.

However, if you're like me, then you might not have a calculator that can work with fractions at hand right now or be able to add them up without second-guessing yourself on your own.

So, if you run into this problem then you can take the fraction part of the problem and just work it like a division problem.

3/4 = .75

1/4 = .25

Then, you can take the respective decimals, and bring them back to their whole number.

5.75

4.75

2.25

6.75

Then just add them all up:

5.75+4.75+2.25+6.75= 19.5

Now, if you need to revert it back to a fraction it could get tricky again. Luckily, this time we got an easy one! .5 which equals 1/2.

So, your answer would be 19 and 1/2.

*** If this answer is wrong I sincerely apologize. I believe it is correct but we all make mistakes.

Amy wants to sell at most 25 cookies and at least 10 sprites

Inga [223]

Answer:

$x\leq 25\\y\geq 10\\.50x + y\geq 30$

Step-by-step explanation:

It is given that,

Amy wants to sell at most 25 cookies ,

Let number of cookies be ' $x$ ' , then $x$ should be less than or equal to 25

Which is represented by $x\leq 25$ ,

Further,

Let number of sprites be ' $y$ ', then ' $y$ ' should be greater than or equal to 10

Which is represented by $y\geq 10$

Also,

Given,

she profits $.50 on every cookie

and $1.00 on every sprite.

So total profit on selling cookies would be

= Profit on each cookie times the number of cookies

= $.50\times x$

= $.5x$

Similarly, total profit on selling sprites would be

=profit on each sprite times the number of sprites

= $1.00\times y$

= $y$

Now, combining these two should be greater than or equal to $30

representing this through an equation,

$.50x+y\geq 30$

Thus the sysytem of equations is given as:

$x\leq 25\\y\geq 10\\.50x + y\geq 30$

I need help with the steps. The answer is (5,2)

Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

$y+3+y=7\\2y+3=7\\2y=4\\y=2$

Next, now that we have the value of y, substitute it into either equation to solve for x:

$x+2=7\\x=5\\\\x=2+3\\x=5$

<u>And this is how you get your final answer (5,2).</u>
