Anna has $430. She wants to buy a phone that costs $275. Anna will also have to pay a sales tax of 7%.
ki77a [65]
19.25 (tax)
294.25 (total price)
135.75 (money left)

REASONING:

In this word problem it says Anna has 430 dollars. The phone costs 275 dollars. It also says that when she buys the phone, she will have to pay a tax of 7%.

To find how much tax she will pay, we must do [275] x [0.07]

After inputting this into a calculator, you will get 19.25 (tax)


To find the total price, all you have to do is add 19.25 to 275. When you do this, you will get 294.25 dollars (total price)


To find how much money she has left,

430-294.25=135.75 (money left)

Help!!!!!!!!!!!!!!!!!!!!
lapo4ka [179]
Well...   the segment FG = 4x + 3, the segment GH = 7x - 12, now, the
 
segment FH = FG + GH, those two fellows added up, and we know that FG and GH are both equal halves because G is the midpoint.

thus, FG = GH
or

\bf 4x+3=7x-12\implies 3+12=7x-4x\implies 15=3x&#10;\\\\\\&#10;\cfrac{15}{3}=x\implies \boxed{5=x}\\\\&#10;-------------------------------\\\\&#10;thus\qquad &#10;\begin{cases}&#10;\overline{FG}=4x+3\\&#10;4(5)+3\\&#10;23\\&#10;------\\&#10;\overline{GH}=7x-12\\&#10;7(5)-12\\&#10;23&#10;\end{cases}\impliedby equal\ halves&#10;\\\\\\&#10;\overline{FH}=23+23\implies \overline{FH}=46\implies 6y-2=46&#10;\\\\\\&#10;6y=46+2\implies y=\cfrac{48}{6}

and fairly sure, you know how much that is.
