Can anyone please help ​

$210

Step-by-step explanation:

if she is selling each bar for 175% then she is also selling the pack for 175%.

Three packs is $120

Do 120* (1 + 0.75) = 210

only 10/60 isn't equivalent

hope this : )

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
