In 1950, Town A had a population of 200 people and the population increased by 200 people each year. In 1950, Town B had a popul
schepotkina [342]

Answer:

Town B will eventually overtake Town A

in 1990 Town B will have a larger population

Step-by-step explanation:

To work out how big town A will be in 1990 you need to do 200 + (200x40) because you add 40 years worth of increased population onto the starting population

To work out how big town B will be in 1990 you need to use the equation 200 X 1.1^40 because to work out plus 10 percent you need to do 1.1 and do it to the power of 40 for how many years

in 1990 town a will have a population of 8200 and town B will have a population of 9051.85

A store sells four-packs of permanent markers in assorted colors for $3.19 per pack. All spiral-bound notebooks, whether wide-ru
diamong [38]

Answer:

D. 1.06(3.19x + 1.20y + 1.20z)

Step-by-step explanation:

Since marker packs are 3.19 each, the cost of the marker packs she buys can be represented by 3.19x.

All spiral notebooks are 1.20 each, so the cost of the wide ruled notebooks can be represented by 1.20y.

The cost of the college ruled notebooks can be represented by 1.20z.

In the expression, all of these terms have to be added together and multiplied by 1.06 to calculate the sales tax.

So, the expression will be 1.06(3.19x + 1.20y + 1.20z)

D is the correct answer
