Pilar used five reusable shopping bags on a recent purchase she made at a grocery store. each bag decreased the amount she spent by 5 cents. what was the change to the amount pilar spent at the grocery store by using the reusable bags?

-25 is the answer hope this help

-75 cents

Step-by-step explanation:

Pilar decreased the amount she spent at the grocery store by 15 cents for each reusable bag she used.

Therefore, the amount she spent changed by -15 cents for each reusable bag she used.

Multiply the number of bags by -15 cents per bag to find the total change to the amount Pilar spent.

5 bags × (-15 cents per bag)=-(5 bags × 15 cents per bag)

=-75 cents

Therefore, the amount Pilar spent at the grocery store changed by -75 cents because she used 5 reusable bags.

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:
