Ruth works at a farmer's market and gets paid $50. she also gets paid $0.65 for each jar of jelly "j" she sells. which equation represents her salary, "s". a) j = 0.65 (50 + s)
b) s = 0.65j
c) s = 50j + 0.65
d) s = 50 + 0.65j

Step-by-step explanation:

Ruth's salary is s(j), where s represents salary and j the number of jars she sells.

At the very beginning, she receives $50.  Only answer 'd' could be correct.

But also, the equation has the variable part 0.65j, or

$0.65j, which is directly proportional to the unit price of the jars of jelly.

Summing up the fixed and variable parts, we get

s = $50 + ($0.65j), or s = $50 + ($0.65/jar)j    This is Answer D.
