Answer:

4 years

Step-by-step explanation:

Forty rabbits , increasing by 50% each year

first year : 40+(40*50%)= 60 rabbits

second year: 60+(60*50%)=90

third year : 90+(90*50%)=135

fourth year: 135+(135*50%)= 202.5 ≅ 203 rabits

after 4 years

40(1+0.5)^4= 202.5 ( almost 200)

Fifteen more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by
lapo4ka [179]
2x-15=3(x-15) 
2x-15=3x-45
2x+30=3x
30=x

Let's check this work!

2(30)-15=3(30-15)
60-15=3(15)
45=45

She worked 45 hours each week

 *the reason it is 2x-15 and not 15+2x is because "more than" is considered a "turn around word" meaning it is the opposite
