Instructions: • Write the algebraic expression for each problem:
1. Mike's dog had puppies. Mike has sold 3 of them. Let n be the number of puppies Mike has now.
Write an expression that tells the original number of puppies.

n = puppies born - 3

Step-by-step explanation:

Mike's dog had ? puppies, so you need to have the number of puppies born. Since he sold 3 of them, you need to subtract three from the number of puppies born. n is the number of puppies Mike has now, which equals the number of puppies born minus the number of puppies he gave away, which is 3.

Hope this helps!

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

a is the best answer choice
