The answer is -31 2/5<span />
I have no idea how to do this problem i dont know what a is
258 3/4 cubic meters
Explanation:
Use this formula for volume of rectangular prism: length x width x height
In this case it would be:
15 • 11 1/2 • 1 1/2 = 258 3/4
VOLUME= 258 3/4 cubic meters
Com.ment me if u have any questions
If my answer is correct, braibliest please!

Answer:
Brownies made the most money
Step-by-step explanation:
Let c = cookies
b = brownies
We sold 51 items so c+b = 51
Cookies are .75 and brownies are 1.25
.75c + 1.25 b = 53.25
We have 2 equations and 2 unknowns
c = 51-b
Substituting into the second equation
.75(51-b) + 1.25b = 53.25
Distribute
38.25-.75b +1.25b = 53.25
Combine like terms
38.25+.5b = 53.25
Subtract 38.25 from each side
38.25 +.5b -38.25 = 53.25 -38.25
.5b =15
Divide each side by .5
.5b/.5 = 15/.5
b = 30
Now find c
c =51-b
c = 51-30
c = 21
They sold 30 brownies and 21 cookies
30 brownies * 1.25 =37.50
21 cookies *.75 = 15.75
Brownies made the most money
I believe the answer is (a+c, b) but I'd double check to make sure.
