First off, nicely done on the exponents. You'd be surprised on how bad some look ,:D
a)

b)
Let
x-------> the original price of the bed sheets
we know that
Nancy purchased some bed sheets for $
they were on sale
% off
so
%-
%=
%
%=

therefore
the answer is
the original price of the bed sheets was $
no. of boys : no.of girls
100 : 140
to get the simplest ratio you gotta divide both with a common factor
Because both 100 and 140 share a common factor of 20
the simplest ratio will be
100/20 : 140/20
5:7
5:7 is the simplest ratio
Answer:
The price of an adult ticket is $9 and the price of a student ticket is $6
Step-by-step explanation:
Create a system of equations where x is the price of an adult ticket and y is the price of a student ticket:
2x + 7y = 60
3x + 11y = 93
Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2, to cancel out the x terms:
6x + 21y = 180
-6x - 22y = -186
Add them together:
-y = -6
y = 6
Then, plug in 6 as y into one of the equations to solve for x:
2x + 7y = 60
2x + 7(6) = 60
2x + 42 = 60
2x = 18
x = 9
So, the price of an adult ticket is $9 and the price of a student ticket is $6
