2.80×50 step by step
2 burgers and a soda the soda cost 2 dollars since sale tax was added to his meal at the rate of 10% so 20 cents added 19.80 minus 2.20 (I cant think cause im being rushed lol) which equals 17.60 divided by 2 8.80 dollars each
x = -2y + 5
-2y + 5 = x
-2y = x - 5
f^-1(x)= -x/2 + 5/2
6x
