Given: 4p + 5q = 7
Multiply both sides by 3 to get the EQUIVALENT equation: 12p + 15q = 21
Subtract 12p from both sides to get:
15q = 21 - 12pNow onto the question!!
Quantity A: 12 + 15q
Quantity B: 20
Replace 15q with
21 - 12p to get:
Quantity A: 12 + (
21 - 12p)
Quantity B: 20
Simplify to get:
Quantity A: 33 - 12p
Quantity B: 20
Subtract 33 from both sides to get:
Quantity A: -12p
Quantity B: -13
Let's
test some valuesIf p = 0, then we get:
Quantity A: -12(0) = 0
Quantity B: -13
Quantity A is greater
If p = 2, then we get:
Quantity A: -12(2) = -24
Quantity B: -13
Quantity B is greater
Answer: D
Cheers,
