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.

Can someone answer this?
Paha777 [63]

Answer:

x=1

Step-by-step explanation:

Convert decimals to fractions:

11/5x + 11/5 / 4= 1.1

Simplifies the fraction:

11x+11 / 20= 1.1

Remove denominator (then multiply by 20 on both sides):

11x+11=22

Move the x to the left:

11x= -11+22 → 11x=11

Simplify:

11x=11 → x=1
