Question:

Matt and Ming are selling fruit for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Matt sold 3 small(?) boxes of oranges and 14 large boxes of oranges for a total of $203. Ming sold 11 small boxes of oranges and 11 large boxes of oranges for a total of $220. Find the cost each of one small box of oranges and one large box of oranges.

Cost of one small box is $7 and cost of one large box is $13

Explanation:

Given:

Cost of 11 small boxes and 11 large small boxes of oranges sold by Ming=$220

Cost of 3 small boxes and 14 large small boxes of oranges sold by Matt=$203

To Find:

Cost of one small orange box=?

Cost of one large orange box=?

Solution:

Let the cost of one small box be $a  

Cost of one big box be $b.

Matt sold 3 small boxes of oranges and 14 large boxes of oranges for a total of $203  

Then,  

3 x $a + 14 x $b = $203  

3a + 14b = 20………………………………..(1)

Ming sold 11 small boxes of orange and 11 large boxes of orange for a total of $220.  

Then,  

11 x $a + 11 x $b = $220  

11a + 11b = 220  

a + b = 20……………………………………(2)

Now,  solving the above equations,

From equation(2) we get

a = 20 – b  

So, put value of a in (1)

3(20 – b) + 14b = 203  

60 – 3b + 14b = 203  

11b = 203 – 60  

11b = 143  

b=13

Thus,

a = 20 – 13 = 7

a=7

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
