Answer this question:Noah, who loves his Grammy, calls her every week to talk about his day. If each call lasts 30 minutes and he is charged $0.05 per call minute, how much would he be billed if he makes the calls for a year?
A year has 52 weeks, so if he talks for 30 minutes every week, the total number of call hours is 52 * 30 = 1560 minutes. Since he is charged 0.05 cents per call, the total cost is 1560 * .05 = 78 dollars.
The answer is 78.

First figure out how many tiles are in one row by dividing the kitchen's width by each tile's width: 48 inches / 6 inches / tile = 8 tiles in one row. Then figure out how many rows of tiles there are by dividing the kitchen's height by each tile's height: 72 inches / 6 inches / tile = 12 rows of tiles. Then multiply the number of rows by the number of tiles per row to find the total number of tiles Kimiko needs to buy: 8 tiles / row * 12 rows = 96 tiles.
The answer is 96.
