Tickets to a show cost $5.50 for adults and $4.25 for students. A family is purchasing 2 adult tickets and 3 student tickets.
jarptica [38.1K]

The exact cost is $23.75 for the show, and the exact change they should get is $1.25.

An adult ticket to the show costs $5.50

A student ticket to the show costs $4.25.

A family buys two adult tickets and three student tickets. This would imply that the total cost of two adult tickets would be

⇒ 2 × 5.5 = $11

It also implies that the total cost of three student tickets is

3 × 4.25 = $12.75

The total cost of two adult tickets and three student tickets is

⇒ 11 + 12.75 = $23.75

If the family pays $25, the exact change they should get is

⇒ 25 - 23.75 = $1.25

Thus, the exact cost is $23.75 for the show, and the exact change they should get is $1.25.

aliina [53]

Step-by-step explanation:

they forget the last step which is to take the square root of the sum

7) a = 4

b = 17

a² + b² = c²

4²+ 17² = c²

16 + 289 = c²

305 = c²

√305 = c

17.464249196572980 = C
