Answer:

She used 4 test tubes for the last experiment

Step-by-step explanation:

Total test tubes needed = 14

Experiment 1 = 2 test tubes

Total test tubes remaining = total - used

= 14 - 2

= 12 test tubes

Remaining experiment = 4 - 1

= 3

Test tubes used for the remaining experiment = test tubes remaining / Experiment remaining

= 12 / 3

= 4 test tubes

How many test tubes did she use for the last experiment?
