Laura estimated the total cost of attending a private four-year university using the information in the table. Category Estimate
4vir4ik [10]

Answer:

$124,400

Step-by-step explanation:

The scholarship pays for 30% of her tuition.  This leaves her responsible for 100-30 = 70% of it.  70% = 70/100 = 0.7; this makes her part of the yearly tuition

0.7(29500) = 20650

She is still responsible for her $9600 room and board per year.  Her books are paid for by the scholarship; however she still has the lab and facility fees at $850 per year.

Altogether this gives her a total of

20650+9600+850 = 31100 per year.  Over the course of 4 years, this will cost her

31100(4) = 124400

blsea [12.9K]

Answer:

<h2>A: -12</h2>

Step-by-step explanation:

Put the values of a = -46 and b = 34 to the expression a + b:

-46 + 34        <em>use the commutative property a + b = b + a</em>

= 34 + (-46) = 34 - 46 = -12
