The cost of admission to the Baytown Zoo is $10.50 for each senior citizen, $15.75 for each adult, and $8.25 for each child. What if 2 more tickets for admission are purchased? If the two additional tickets cost $16.50, determine what type of tickets the family purchases. Explain how you can determine the answer without calculating.

Child ticket

Step-by-step explanation:

Cost per senior citizen = $10.50

Cost per adult = $15.75

Cost per child = $8.25

Since the cost of the 2 additional ticket is $16.50

Then the only ticket of which two can be purchased with that amount is :

$16.50 / 2

= $8.25

Cost of children ticket.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
