You divide the Price by the Quantity $$$/quantity to get cost per unit

by the way your previous question for pens should be 89.9 cents or rounded up to 90 cents

(I did the following questions regarding how much you get per dollar, not how much a unit cost)

You are getting about 417 square feet of lawn food per dollar or about 416 square feet of lawn food per dollar. First option is the better option

You are getting about 111 sheets of paper for a dollar or 119 sheets for a dollar. Second option is the better option

Make them all fractions over 4, so 3 would be 12/4, and 1 1/4 would be 5/4 so add them together
12/4+5/4= 17/4 then divide by 4 to reduce it, to get 4 1/4

Answer:

Width of rectangle = 6 m

Length of rectangle = 11 m

Step-by-step explanation:

Let width of rectangle = w

Length of rectangle = 3w-7

Area of rectangle = 66 m²

We need to find length and width of rectangle

The formula used is: $Area=Length \times Width$

Putting values and finding w

$Area=Length \times Width\\66=(3w-7)(w)\\66=3w^2-7w\\3w^2-7w-66=0\\$

Solve using quadratic formula: $w=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

We have a=3, b=-7, c=-66

Putting values and finding w

$w=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\w=\frac{-(-7)\pm\sqrt{(7)^2-4(3)(-66)}}{2(3)}\\w=\frac{7\pm\sqrt{49+792}}{6}\\w=\frac{7\pm\sqrt{841}}{6}\\w=\frac{7\pm29}{6}\\w=\frac{7+29}{6}\:,\:w=\frac{7-29}{6}\\w=6, w=-3.6$

We get values of w as w=6 and w=-3.6

As we know width cannot be negative, so considering w = 6

So, Width = 6

Length = 3w-7 = 3(6)-7 = 18-7 = 11

So, Width of rectangle = 6 m

Length of rectangle = 11 m

ELEN [110]

I believe it is 3.75 miles. 5 2/5=5.4 and 1 11/25=1.44. 5.4/1.44=3.75.
