X/25 = $2.79/16.4

X = ($2.79/16.4)*25

Answer 2

Answer: $4.25

Explanation:

Given : Granola costs $2.79 for 16.4 ounces.

i.e. 16.4 ounces of granola costs = $2.79

Then, the cost of 1 ounce of granola = Cost of 16.4 ounces divided by 16.4

=
`\$2.79/16.4=(\$2.79)/(16.4)=(\$27.9)/(164)`

Then, the cost of 25 ounces of granola = 25 x Cost of one ounce of granola

=
`25*(27.9)/(164)\\\\=4.25304878049\approx4.25`

Hence, the cost of 25 ounces of granola = $4.25
