Marty bought a shirt for 9.50, sandals for 15.50,shorts for 11.75, and sunscreen for 5.25. use mental math to find the total amount he spent

ok so, this is a pretty easy question, what you need to do is to round every number to the nearest whole numer (10,16,12,5) add them up and then just add the cents

answer = 42

mark me as the brainliest !

the first one, all those points on the line just make a strait line.

thats not a system of equations, that is a solution
