DOGS In 2004, there were about 73.9 million pet dogs in the U. S. In 2017, there were about 89.7 million pet dogs in the U. S. Write a linear equation to represent the number of pet dogs d, in millions, t years after 2000. Round to the nearest hundredth.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

answer: $53750

steps:

list the principal and interest after the n-th year:

n       principal   simple interest

1     12500     375

2     25000     750

3     37500     1125

4     50000     1500

sum: $50000     $3750

total at end of year 4: $53750
