a box cost $2.48, but it is on sale for $1.49. How much do you save on one box when bought on sale? Now how much would you save
Thepotemich [5.8K]

Answer:

1. $0.99

2. $1.98

Step-by-step explanation:

1. From the question we have

Cost of box = $2.48

Selling price = $1.49

That is the box is discounted from $2.48 to $1.49

Therefore, amount saved = $2.48 - $1.49 = $0.99

2. The amount saved from buying a second box is hence;

2 × $0.99 = $1.98

Hence, as the number of boxes bought increases, the amount saved increases

Help me with this math problem please
mrs_skeptik [129]

Answer:

y=8

RS=77, ST=31

Step-by-step explanation:

Note that the entire segment RT is the combined lengths of RS and ST. So:

RT=RS+ST

We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:

108=(9y+5)+(3y+7)

On the right, combine like terms:

108=(9y+3y)+(5+7)

Add:

108=12y+12

Subtract 12 from both sides. The right cancels:

96=12y

Divide both sides by 12:

y=8

So, the value of y is 8.

To find RS and ST, substitute 8 for y. So:

RS=9y+5

Substitute 8 for y:

RS=9(8)+5

Multiply:

RS=72+5

Add:

RS=77

Do the same for ST:

ST=3y+7

Substitute 8 for y:

ST=3(8)+7

Multiply:

ST=24+7

Add:

ST=31
