(6) If the store likes to keep 30 tiles in stock at all times how many bundles do they need to order now, after selling the 150 tiles to the customer? Think about how many you had left over from the customer when ordered 150 tiles.


function:
number of tiles: 12b+38
Where;
b=number of bundles
150+30 = 12b+38
Solve for b:
150+30 = 12b+38
180 = 12b+38
180-38 =12b
142 =12b
142/12 =b
11.8 =b
12 bundles
