Question

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?

PLZ NEED HELP

Answer 1

0.85x = 34

x = 40

Answer 2

its in percent (85%) i don't think it should be in decimal when i tryed it i got the answer as 28.9 tonnes
