Answer:

X = 9 months

are the same, you should equate the two cost. First establish the equations


Let A be the cost of first payment method


B is the cost of the second payment method


X is the number of months

38x + 15 = 31x + 78


7x = 63


X = 9 months

A cube has a volume of greater than 123 cm3. What are the possible lengths of the side of that cube?
