a bug population doubles every 5 days. If you start with 6 bugs, how many bugs will there be in 35 days
Shtirlitz [24]

Answer:

768 bugs

Step-by-step explanation:

You can rewrite this problem as a function as time where the bug population is f(x), and x is the number of days since the start.

f(x)=6*2^(x/5)

Here, the 6 represents the number of bugs that you start with, the two shows that they double every day, and the /5 shows that they double every 5 days.

By plugging in 35, you get 6*2^7, which is 768.

Lesley works as a cars salesperson. She makes a monthly base salary of $1500. She also earns a 4% commission on all sales beyond
Troyanec [42]

Answer:

$1,740

Step-by-step explanation:

Setting up an equation to solve for Lesley's total salary would be the sum of her monthly base salary ($1,500) and the amount of her commission for any sales over $20,000:

Salary = $1,500 + (sales - $20,000)(0.04)

Since Lesley sold $26,000 in sales this month, we can calculate her total salary and commission:

Salary = $1500 + ($26,000-$20,000)(0.04) or $1500 + ($6000)(0.04)

Salary = $1500 + $240 = $1,740.00
