Many people are trying to reduce their carbon footprint. Amrita’s carbon footprint this year was
85% of last year’s footprint. If her carbon footprint this year is 34 tonnes, what was her carbon
footprint last year?
please help!!!!
0.85x = 34
To find out Amrita's carbon footprint last year, we can set up a proportion using the given information.
Let x be Amrita's carbon footprint last year.
According to the information provided, Amrita’s carbon footprint this year was 85% of last year’s footprint. This can be written as:
85% = 0.85 (in decimal form)
So, we can set up the proportion:
0.85 = 34 / x
To solve for x, we can cross-multiply:
0.85 * x = 34
x = 34 / 0.85
x ≈ 40
Therefore, Amrita's carbon footprint last year was approximately 40 tonnes.
