Erica earns a rebate each month on her meals and movie tickets. she earns $3 for each movie ticket and $0.80 for each meal. last month erica purchased 15 meals and earned $18. part a: create an equation that will determine the number of movie tickets she purchased. (3 points) part b: solve this equation justifying each step with an algebraic property of equality. (6 points) part c: how many movie tickets did erica purchase last month?

A) Let t represent the number of tickets Erica bought. The the equation describing her rebates can be written as

... 3t + 0.80×15 = 18

B) Here's the solution to the equation.

... 3t + 12 = 18 . . . . . . simplify; rules of arithmetic

... 3t = 6 . . . . . . . . . . .subtract 12; subtraction property of equality

... t = 2 . . . . . . . . . . . . divde by 3; division property of equality

C) Erica bougth 2 movie tickets last month.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

answer: idk
