Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
Step-by-step explanation:
Let,
Cost of pretzel = x
Cost of ice cream = y
According to given statement;
the cost of a pretzel is $2 less than the cost of some ice cream.
x = y - 2 Eqn 1
five ice creams cost the same as nine pretzels.
9x = 5y Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 4
Putting y=4.5 in Eqn 1
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5

Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of regular fares paid.
y is the number of reduced fares paid.
1,042 total fares were paid
This means that
A city bus collected $1,140 in fares on a given day. The regular fare is $1.50, and the reduced fare is $0.75.
This means that:

1. The formula for calculation of the volume of the cylinder is V=π*r²*h, where r - the radius of the base, h - the height of the cylinder.
2. According the formula above:
V=π*64*8=512π (cm³).
Answer: 512π
