What does find the constant rate of change mean?
natulia [17]

The change of the cost changes when the pounds of ham changes. When the pounds of ham is 0, it costs 0 dollars. When the pounds of ham is 3, it costs 12 dollars. The cost changes consistently with the pounds of ham. They change together. Every time the pounds of ham goes up by 3, the cost goes up by 12.

Evaluate.<br> 1/2 (11)(15 + 17) =
Andrei [34K]

Answer: 176

Step-by-step explanation:

To evaluate the equation we have to remove the parentheses and add 15 + 17...

1/2 (11)(15 + 17) =

= 11 * 32 * 1/2

Now, we have to turn it into a fraction and multiply it...

\frac{1*11*32 }{2}

= \frac{352}{2}

352 ÷ 2 = 176

I hope this helps!

The admission fee at an amusement park is $2.00 for children and $6.80 for adults. On a certain day, 388 people entered the park
spin [16.1K]

Answer: 188 children and 200 adults were admitted.

Step-by-step explanation:

Let x represent the number of children that were admitted that day.

Let y represent the number of adults that were admitted that day.

On a certain day, 388 people entered the park. It means that

x + y = 388

The admission fee at the amusement park is $2.00 for children and $6.80 for adults. The admission fees collected that day totaled $1736. It means that

2x + 6.8y = 1736- - - - - - - - - - - 1

Substituting x = 388 - y into equation 1, it becomes

2(388 - y) + 6.8y = 1736

776 - 2y + 6.8y = 1736

- 2y + 6.8y = 1736 - 776

4.8y = 960

y = 960/4.8

y = 200

x = 388 - y = 388 - 200

x = 188
