Two hiking groups made the purchases shown below. What is the cost of each item. GROUP 1: 6 muffins, 12 granola bars, Total=$26.70 GROUP 2: 8 muffins, 15 granola bars, Total=34.00

Price of each muffin = $1.25

Price of each granola bar = $1.6

Step-by-step explanation:

Group 1:

6 muffins, 12 granola bars

Total money paid = $26.70

Group 2:

8 muffins, 15 granola bars,

Total money paid = $34.00

To find:

Price of each item?

Solution:

Let the price of one muffin = $

Let the price of one granola bar = $

As per group 1, the equation can be written as:

As per group 2, the equation can be written as:

.... (2)

Let us use elimination method to solve for and .

Multiplying equation (1) with 8 and subtracting (2) from it:

Using equation (1):

Therefore, the answer is:

Price of each muffin = $1.6

Price of each granola bar = $1.25

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
