Answer:
4(25) + 3(15) +10 = $155
Explanation:
first you plug in the information so since there are 4 tickets for $25 each, that part of the expression would be 4(25). Next you add the t-shirts so since there are three for $15 each that part of the expression would be 3(15). Lastly you add the poster. since there is only one and it costs $10 you would just add 10. This makes your expression 4(25) + 3(15) +10. (the parenthesis mean you multiply the number inside by the number outside).
