Answer:

$3.19

Step-by-step explanation:

so he starts with $18.90 and we know that he spent $2.95. So we will subtract  $2.95 from $18.90. So we are left with $15.95. But now its says he bought 5 items with $15.95. So we will divide 15.95 by 5. So the price of the item that he bought 5 of is $3.19

If you are at a higher level you can use this method:

make and equation of: 5x + 2.95 = 18.90

with this you would subtract 2.95 and then divide by 5 just like we did above.

Answer:

d. 15.95

Step-by-step explanation:

So if one item cost $2.95 and he bought 5 other items that were the same price, we first have to subtract $2.95 from the total which is $18.90.

18.90 - 2.95 = 15.95

Now, to find the cost of the other five items we divide the amount of money left by 5.

15.95 / 5 = 3.19

So each of the other five items costs $3.19.

To find the total cost of the five items together, we multiply 3.19 by 5.

3.19 x 5 = 15.95

Please see attached picture for full solution.

according to Interstate Highway Standards, U.S. and state highway traffic lanes must be at least 12 feet wide. Write an inequality to represent the widths that traffic lanes can be.

Answers

So,

"at least" means that is the minimum acceptable amount.  So we will use the "greater than or equal to" symbol.

Let "w" represent the width of the traffic lane.

w ≥ 12 ft.
