Elaine has a $25 gift card. She uses the card each month to purchase a magazine for $3.50 at the
bookstore. How much money will Elaine have
remaining on her gift card after 7 months?

$0.50

Step-by-step explanation:

multiply 3.50 by 7 and you get 24.5. $25.00-$24.50= $0.50

0.5

Step-by-step explanation:

Well lets start with a basic equation.

$25=3.50(7)

25= 24.5 multiply 3.50 and 7

25-24.5=0.5 subtract the total from the whole

After using the card for 7 months she will have 5 cents left on her card.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
