Answer:

Last year, the average cost of a traditional Thanksgiving dinner was $48.91.

Step-by-step explanation:

If this year the cost of a traditional Thanksgiving dinner was decreased by 1.76% compared to last year, then

last year cosr - 100%

this year cost - 100%-1.76%=98.24%

So,

$x - 100%

$48.05 - 98.24%

Write a proportion:

[tex]\dfrac{x}{48.05}=\dfrac{100}{98.24}[/tex]

Cross multiply:

[tex]98.24x=48.05\cdot 100\\ \\98.24x=4,805\\ \\x\approx 48.91[/tex]

Last year, the average cost of a traditional Thanksgiving dinner was $48.91.
