Answer:
There is 57 snails after 14 weeks
Step-by-step explanation:
Creating an equation:
tripling every week means 3x
NOTE: x is defined as the number of weeks
started with 15 snails means at day 0 (x = 0 also known as y intercept)
y = mx + b m is the slope, b is the y intercept
our equation: y = 3x + 15
after 14 weeks (x = 14):
y = 3(14) + 15
y = 42 + 15
y = 57
