Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each. Devin has a coupon that gives a 5% disc

Svetach [21]

Given :

Devin is buying 2 concert tickets. The concert tickets have a regular price of $40 each.

Devin has a coupon that gives a 5% discount off of the regular price of the tickets. He will then pay a 10% purchasing fee on the discounted price of the tickets.

To Find :

Devin's total cost of the two tickets after the discount and the fee.

Solution :

Discount on price, D = 40×0.05 = $2 .

Price of product after discount, P = $( 40 - 2 ) = $38 .

Now, total price after adding purchasing fee is :

T = P + (P×0.10)

T = 38 + (38×0.10)

T = 38 + 3.8

T = $41.8

Therefore, Devin's total cost of the two tickets after the discount and the fee is $41.8 .

Hence, this is the required solution.

Hats and mittens are on sale at the store! One woman was able to buy 5 hats and 4 pairs of mittens for $30.

morpeh [17]

The price of one hat is $2 and price of one pair of mittens is $5.

Step-by-step explanation:

Let,

Price of one hat = x

Price of one pair of mittens = y

According to given statement;

5x+4y=30 Eqn 1

2x+3y=19 Eqn 2

Multiplying Eqn 1 by 2

$2(5x+4y=30)\\10x+8y=60\ \ \ \ Eqn\ 3$

Multiplying Eqn 2 by 5

$5(2x+3y=19)\\10x+15y=95\ \ \ \ Eqn\ 4$

Subtracting Eqn 3 from Eqn 4

$(10x+15y)-(10x+8y)=95-60\\10x+15y-10x-8y=35\\7y=35\\$

Dividing both sides by 7

$\frac{7y}{7}=\frac{35}{7}\\y=5$

Putting y=5 in Eqn 1

$5x+4(5)=30\\5x+20=30\\5x=30-20\\5x=10$

Dividing both sides by 5

$\frac{5x}{5}=\frac{10}{2}\\x=2$

The price of one hat is $2 and price of one pair of mittens is $5.
