$F$

#### Work Step by Step

As per the given statement let us consider $a$ as cost of 1 candy bar and $b$ as cost of 1 bag of chips. Thus, $2a+3b=5.45$ and $5b=6.25$ $b=\frac{6.25}{5}=1.25$ Plug $b=1.25$ in $2a+3b=5.45$ $2a+3(1.25)=5.45$ $a=0.85$ Therefore, the cost for one candy bar is $0.85$ dollar. Hence, the correct answer is $F$.
