Question

the bubble tea room sells bubble teas. each bubble tea costs $4.
how much do 3 bubble teas cost?
(chart: number of bubble teas: 1, 2, 3; total cost ($): 4, 8, 12)
how is the number of bubble teas related to the total cost?
total cost = □ × number of bubble teas

Explanation:

Step1: Identify the cost per tea

Each bubble tea costs $4, so the rate is $4 per tea.

Step2: Relate number to total cost

The formula for total cost is (cost per tea) × (number of teas). From the table, 1 tea costs 4, 2 cost 8 (4×2), 3 cost 12 (4×3). So the multiplier is 4.

Answer:

4
