Answer:

Tom is incorrect

The cost of using the air pump has increased by 150%

Tom is incorrect

percent change = [ (difference between initial and final value) ÷ initial value] × 100

⇒ [ (50 - 20) ÷ 20) × 100 = 150%

Therefore, the cost of using the air pump has increased by 150%

Write the fraction<br> 2/7<br> as an equivalent fraction with the given denominator 28.
Nataly [62]

Answer:

8/28

Step-by-step explanation:

2/7  = ?/28

Well we have both of the denominators, and all they did was multiply the denominator of "7" by 4 to get "28" as the other denominator, so now all we have to do is multiply the first numerator by 4 to get the equivalent fraction.

2*4/7*4 = ?/28

8/28 = ?/28

The given numerator will be 8.

2/7 is equivalent to 8/28

1 pound of carrot and 1.5 pounds of squash cost $7.00.

1c + 1.5s = 7 ----------------- [ 1 ]

4.5 pounds of carrot and 1.75 pound of squash cost $14.00.

<u>Sub s = 3.5 into [ 1 ]:</u>

1c + 1.5 (3.5)  = 7

1c + 5.25 = 7

1c = $1.75
