Answer:
$2.96
Step-by-step explanation:
1.15x = 3.40 x = last year's price. If there price was exactly the same, I would put 1x, but this year's price is 15% or .15 higher.
1.15x = 3.40 Divide both sides by 1.15 and round to the nearest cent.
x = 2.96
Check:
Last year + 15% (.15)
2.96 + .15(2.96)
2.96 + .44 rounded to the nearest cent
3.40
