The population of a town is growing exponentially and can be modeled by the
svp [43]

The population of the town in 1960 is 48.80 thousands

<h3>How to determine the population in 1950?</h3>

The equation of the model is given as:

f(t) = 42e^(0.015t)

1960 is 10 years after 1950.

This means that:

t = 10

Substitute t = 10 in f(t) = 42e^(0.015t)

f(10) = 42e^(0.015 * 10)

Evaluate

f(10) = 48.80

Hence, the population of the town in 1960 is 48.80 thousands

two families are saving up for a summer trip the smith family originaly has 1000 dollars and will save 50 dollars every week the
SCORPION-xisa [38]
1000 + 50x = 500 + 75x

First move 500 by subtracting it from 1000.
500 + 50x = 75x

Now subtract 50x from 75x.
500 = 25x

Then divide 500 by 25.
20 = x

They would've saved the same amount($2,000) on the 20th week.
