To upgrade her kitchen, Amanda is changing out the doorknobs/pulls. She's replacing 18 cabinet knobs, which cost $2.50 each and 8 drawer pulls which cost $4.00. How much will the kitchen upgrade cost her? Think carefully first, then make a decision:
She's replacing 18 cabinet knobs for $2.50 each for a total of 18 * 2.50 = $45.00. She's replacing 8 drawer pulls for $4.00 each for a total of 8 * 4 = $32.00. The cabinet knobs will cost $45.00 and the pulls will cost $32.00 for a total of 45 + 32 = $77.00 in upgrades. So, the answer is 77.
