Answer:

1. z = 5,  2. w = 9

Step-by-step explanation:

1. 5z - 4 = 21

5z = 21 + 4

5z = 25

z = 25/5

z = 5

2. w/9 + 2 = 3

w/9 = 3 - 2

w/9 = 1

w = 1 x 9

w = 9

I hope this helps :)

What do I need to find?

Your answer is correct.

What information do I need to use?

100% = 240 miles, she has already driven 15% of 240, so she has driven x miles.

How will I use the information?

Set up a proportion. If she has already driven 15% out of 100% of the distance, then you should write \frac{15}{100} for the first fraction. This is proportional to \frac{x(miles)}{240(miles)}. This means that \frac{15}{100} = \frac{x}{240}. Wait, but this is confusing. How on Earth do we solve it? Let's take a closer look. If \frac{x}{240} is supposed to equal 15/100, then this means that x/240 divided by 15/100 should give us the answer. So, even though it looks complicated, all you have to do is cross multiply like this:

\frac{15}{100} = \frac{x}{240} --> 240 * 15 = 100x --> 3600 = 100x

Now isolate x:

\frac{3600}{100} = \frac{100x}{100}

So x = 36, which means she has already driven 36 out of 240 miles. Lucia still has to drive 204 miles to reach her destination.

1.) In this case, 56 = 100% and 25% of the sandwiches were tuna. This means that 75% of the sandwiches were not. If \frac{25}{100} = \frac{x}{56} and you use the same method above, x is equal to 14. If 14 is 25% then that means the other 75% = 14 * 3. So 42 sandwiches were not tuna.

2.) \frac{60}{100} = \frac{x}{450}

--> 27000 = 100x

---> \frac{27000}{100} = \frac{100x}{100}

He still has $270 left to pay.
