Answer:

The percentage is 26.6%

Step-by-step explanation:

Here, we want to

work

out the percentage change

To do this, we use the percentage change formula

This is,

percentage change = new value-old value)/old value * 100%

= (100-78.98)/78.98 * 100%

21.02/78.98 * 100% = 26.6%

Julie works in chicago and has to pay $14 per day on tolls and $76 a day for gas. If she makes $19 an hour how many hours must s
enot [183]

Answer:

19 hours.

Step-by-step explanation:

T = -14 -76 + 19h

The -14 is the cost for tolls, and the -76 is the cost for gas. The 19h is the amount she'll get per hour if she makes $19/hour. And T is the total profit

We want to solve for h if T = 260

260 = -14 -76 + 19h

+14      +14

274 = -76 +19h

+76    +76

350 = 19h

/19      /19

18.42 = h

She must work 19 hours.

Hope this helps!

zmey [24]

Answer:

She spent 5 hours mowing lawns.

Step-by-step explanation:

To solve, we will just use some algebra

8h + 20 = 60 | Subtract 20 from both sides

8h = 40 | Divide both sides by 8

h = 5

We can confirm this by plugging it back into the original formula.

8(5) + 20 = 60

40 + 20 = 60

60 = 60

Softa [21]
Hey there!

You can find the medians by referring to the line in the middle of both of the boxes. These indicate the median of the sets of data you have. The first median is at 10 and the other is at 12. 

All you need to do to find the difference is subtract the smaller number from the bigger number. 

12 – 10 = 2

Your difference will be 2, making your second option your answer. Hope this helped you out! :-)
