The gift bag contains 5 ounces of peppermint candies and 11 ounces of chocolate mint.
Step-by-step explanation:
Cost of peppermint candies per ounce = 6 cents
Cost of chocolate mint = 22 cents
Cost of bag = $2.72 = 2.72*100 = 272 cents
Weight of bag = 16 ounce
Let,
x be the ounces of peppermint candies
y be the ounces of chocolate mint
x+y=16 Eqn 1
6x+22y=272 Eqn 2
Multiplying Eqn 1 by 6

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 16

Putting y=11 in Eqn 1

The gift bag contains 5 ounces of peppermint candies and 11 ounces of chocolate mint.

So According to this equation
2x + 5 = -1
=> 2x = -1-5 (As when 5 goes to the right side so it sign changes)
=> 2x = -6
=> x = -6/2 (as when 2 goes to the right side it gets divided)
*Ans = x=-3*

Answer:
$16.80
Step-by-step explanation:
Since the shirts are marked down by 30%, you need to multiply the cost of the shirt by the percentage.
$24 × 0.3 = $7.20
Next, subtract the discount from the original price to find the discounted price.
$24 - $7.20 = $16.80
By substitution is how to solve
2x-3y=21
y=3-x
2x-3(3-x)=21
2x-9+3x=21
5x=30
x= 6
now substitute our x value into y=3-x
so we get
y=3-6 = -3
so x=6 and y=-3 hope this helps!!!!! Thank you!
