Using his spending account at the school store, Randy buys pencils which are 12 cents each.  For the first 4 months of school, Randy bought 3, 4, 6, and 9 pencils.  If the function A = .12p represents the amount, A, Randy spent on pencils each month and p is the number of pencils he buys, what is the range of this function?

• {3, 4, 6, 9}
• {0.15, 0.16, 0.18, 0.21}
• {0.36, 0.48, 0.72, 1.08}
• {3.12, 4.12, 6.12, 9.12}
