Liam went to the zoo with his parents and a ticket for the zoo cost's him $5.3. It costs an adult $10.70. How much would it cost
jarptica [38.1K]

Answer:

If 4 more kids came to the zoo with Liam and his two parents, and so did 4 more adults, the price they would pay would be:

5.3(5) + 10.7(6)

90.7

So, it would cost a total of $90.70 dollars for Liam, his two parents, four other friends, and four other parents, to come to the zoo.

Let me know if this helps!

Can anyone help and explain how to do this it’s very confusing?
Margarita [4]

Answer:

Find the slopes; 123 servings

Step-by-step explanation:

When you look at the graph and table, find out which ones have a slope of 1/2

To find slope you have to use this equation

\frac{y - y^1}{x - x^1}

So for each graph and table, calculate the slope using that formula :)

For the second question,

For every 10 students, the amount of juice dispensed was

7*4 + 3*8 = 52

So divide 52 by 10 to get 5.2

Then divide the total amount of juice (640) by 5.2 and that rounds to about 123 servings of juice
