Mike bought a soft drink for 2 dollars and 7 candy bars. he spent a total of 23 dollars. how much did each candy bar cost? write an equation and solve

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
