Answer:

The indifference point is 20 tiles.

Step-by-step explanation:

<u>First, we need to establish the total cost formulas for each store:</u>

<u></u>

Store 1:

Total cost= 10 + 0.99*x

Store 2:

Total cost= 1.49*x

x= number of tiles

<u>Now, we equal both formulas and isolate x:</u>

10 + 0.99x = 1.49x

10= 0.5x

10/0.5=x

20=x

The indifference point is 20 tiles.
