What is the unit price for a piece of cheese if 1.24 pounds costs $11.25?

we know that

The unit price is the cost per unit, and to find the unit price, divide the price by the number of units

so

therefore

the answer is

The unit price is

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:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
