Remember distributive property
a(b+c)=ab+ac

You just have to add or subtract the percent of a number from the original

A) 5percent of 40=2 ( 0.05*40)
Since it’s increase add 2 to 40=42

F) 40percent of 25= 10 (0.4* 25)
25-10=15

Answer:

  • $3.50
  • 24

Step-by-step explanation:

The graph shows you the value stored on the card dropped by $14 when Gina rented 4 videos. Thus the cost of each one is ...

... $14/4 = $3.50

Gina now has $84 on the card, so can rent an additional ...

... $84/$3.50 = 24 . . . . videos

_____

Division is a way to do "repeated subtraction." That is, if we were to subtract $3.50 from $84 repeatedly, we would find we could do it 24 times.
