1. Marcus bought a $40.00 tennis racket. He has a coupon for 20% off. The Sales tax where he bought the tennis racket is 6%. a. How much money will Marcus save with the coupon?

$33.92

Step-by-step explanation:

First, we have to find how much the sale price for the tennis racket is before tax.

100% - 20% = 80%          Marcus has to pay 80% of the original price.

80% * 40 = .8 * 40 = 32

Marcus has to pay $32 for the tennis racket before tax.

6% = .06  (tax percentage)

.06 * 32 = 1.92 ————> tax

Add the tax with the sale price.

32 + 1.92 = 33.92

Marcus has to pay $33.92 for the tennis racket.

I hope this helped and please mark me as brainliest!

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:
