Answer:
325 minutes
Step-by-step explanation:
We can use a ratio to solve
25 minutes x minutes
------------------ = ---------------
1 burger 13 burgers
Using cross products
25*13 = 1x
325 = x
325 minutes

<em>Step-by-step explanation:</em>
<em></em>
<em>The art museum charges a one-time fee of $8.25 plus $2.25 per month.</em>
<em></em>
<em>So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)</em>
<em></em>
<em>Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.</em>
<em></em>
<em>Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)</em>
<em></em>
<em>So, from both the equations it is clear that for only joining the monthly charges are zero.</em>
<em></em>
<em>So, f(0) = 8.25 and g(0) = 10.75.</em>
<em></em>
<em>Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)</em>

Step-by-step explanation:
So
if x is the number she spent on each sister and y is the number she spent on each nephew then
180=3x+2y
she wants to spend 15 dollars more on sisters than nephews
so
x=15+y
solve
we have
180=3x+2y and
x=15+y
subsitute 15+y for x
180=3(15+y)+2y
180=45+3y+2y
180=45+5y
minus 45 both sides
135=5y
divide both sides by 5
27=y
solve for x
x=15+y
x=15+27
x=42
she spent $42 on each sister
The answer should be 5.5 because you have to divide it. The fraction would be 5 over 10
