The answer is A to change an exponent from negative to positive, just move it into either the numerator or denominator depending on where it is to begin with.
Answer:
240
Step-by-step explanation:
240 + 60 = 300 you can tell this by realising that ratio to have 4x one over the other would be 20 per 100, using this rate 3x, 240 and 60
140x 0.3= 42
140- 42= 98
So A. $98 is correct.
