jonny [76]

Answer:

It would cost more to go to the zoo by $6

Step-by-step explanation:

The total amount that each attraction costs can be given by;

Science center

Total cost at the science center=cost per ticket×number of tickets

where;

Total cost at the science center=$36.75

Cost per ticket=c

Number of tickets=3 tickets

Substituting;

36.75=c×3

c=(36.75/3)=12.25 per ticket to go to the science ticket

For 12 students, total cost at the science center=(12.25×12)=$147

Zoo

Total cost at the zoo=cost per ticket×number of tickets

where;

Total cost at the zoo=$51

Cost per ticket=d

Number of tickets=4 tickets

Substituting;

51=d×4

d=(51/4)=12.75 per ticket to go to the zoo

For 12 students, total cost at the zoo=(12×12.75)=$153

Total zoo cost-Total science center cost=(153-147)=$6

It would cost more to go to the zoo by $6

Answer:

The bird dove 44 feet.

Step-by-step explanation:

If the bird starts 37 feet above the ocean and dives from its position to 7 feet below the ocean, the you just add the two numbers and get its total dive.

To draw it draw a graph that goes past to +37 and past -7, then draw a bar representing the birds dive from +37 to -7. The X axis would be time, and the Y axis is the bird's height relative to the surface of the water.
