The Molina family went to a concert together. They purchased 4 concert tickets for $25 each, 3 t-shirts for $15 each, and a poster for $10. Write an expression for the total cost and then find the total cost.

$155

Step-by-step explanation:

Variable

Ticket=T

Shirts=S

Poster=P

4 concert ticket so 4T

3 t-shirts so 3S

Poster is P

So the Expression is: 4T+3S+P=Total cost

To find total cost:

Concert at $25 each for 4 people (multiply)

25*4=$100

3 t-shirts for $15 (multiply)

15*3=$45

Poster is $10

Add the totals together:

100+45+10= $155

Therefore, the total cost is $155 for the things they purchased.

Hope this help!!!

Have a nice day :)

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
