Barney & Noblet customers can choose to purchase a membership for $25 per year Members receive 10% off all store purchases
Law Incorporation [45]

Answer:

  1. $70
  2. y = 25 + 0.9x
  3. $250

Step-by-step explanation:

1. 10% of $50 is $5, so the purchases would come to $50 -5 = $45. Added to the $25 membership fee, the total cost for the year would be

  $45 +25 = $70

2. The member pays $25 even if no purchases are made. Then any purchases are 100% - 10% = 90% of the marked price. So, the total is ...

  y = 25 + 0.90x

3. $25 is 10% of $250, so that is the amount the member would have to purchase to break even on cost.

If you like, you can compare the cost without the membership (x) to the cost with the membership (25+.9x) and see where those costs are equal.

  x = 25 +0.9x . . . . . x is the spending level at which there is no advantage

  0.1x = 25 . . . . . . . . subtract 0.9x

  25/0.1 = x = 250 . . . divide by 0.1

what is the volume of the hamsta snack box with a width of 1 1/2 inches, a length of2 1/2 inches, and a height of 4 inches
jenyasd209 [6]

<u>Given:</u>

The width of the snack box is 1 \frac{1}{2} \ inches=\frac{3}{2} \ inches

The length of the snack box is 2 \frac{1}{2} \ inches=\frac{5}{2} \ inches

The height of the snack box is 4 inches.

We need to determine the volume of the hamsta snack box.

<u>Volume of the box:</u>

The volume of the box can be determined using the formula,

V=L \times W \times H

where L is the length, W is the width and H is the height of the box.

Substituting the values, we get;

V=4 \times \frac{3}{2} \times \frac{5}{2}

Simplifying, we get,

V=\frac{60}{4}

V=15 \ in^3

Thus, the volume of the Hamsta snack box is 15 cubic inches.
