Petra has more stamps
Answer:
44378.496=44,379
Step-by-step explanation:
We can write the equation using a growth equation where:
- P is the starting value
- r is the percent or rate as a decimal
- t is years
We will substitute into the formula P=25,682, r=0.2 and t =3 for 3 years since 2018 is 3 years after 2015.
64x2.40 = 153.6
64x1.90 = 121.6
add 153.6 to 121.6
275.2
