PLS HELP I WILL MARK BRAINLEAST! The fire department is having a BBQ fundraiser. The hot dogs costs $1.50 each and cans of
soda cost $0.75 each. The department uses the algebraic expression 1.50x +0.75y to calculate
customers' total expenses.

a. What does the x variable represent?

b. What does the y variable represent?

c. A family buys 7 hot dogs and 4 sodas. What are their total expenses?

a. The variable X represents the amount of hot dogs

b. the variable Y represents the amount of sodas

c. Their total expense would be $13.50

If you multiply $1.50 by 7 you would get $10.50, then you would multiply $0.75 by 4 and get $3.00.

then you would add 10.50 and 3.00 to get $13.50

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
