Answer:
i'm guessing you're asking which expression is the same as 7(x+4)
i don't know what the other numbers listed are suppose to mean, but when expanded, 7(x+4)=7x+28
anything added together, multiplied together, etc, that equals 7x+28 is your answer
X= shift tan 0.3
x=16.6992≈17

Answer: $5.16</h3>
==================================================
Work Shown:
72% = 72/100 = 0.72
72% of $3.00 = 0.72*3.00 = 2.16
The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars
-------
We can find this answer through this alternative route:
1.72*3 = 5.16
The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%
