Adriana brought a shirt for 35$ plus she paid and additional 8% in sales tax. What was Adriana final cost. Plus show work.
mina [271]

Answer:

$37.08

Step-by-step explanation:

Bought the shirt for - $35

Selling price after tax - $35 + 8%

\frac{8}{100} × \frac{35}{1} = \frac{280}{100} or 2 \frac{4}{5}

\frac{4}{5} is equal to 0.8

= $2 + $0.8 = $2.08

Selling price after tax = $35 + $2.08 = $37.08

Hope this helps!

Look at the photo attached for the question, please help asap!
chubhunter [2.5K]

Answer:

<em>y ≥ - 0.8 </em>

Step-by-step explanation:

\sqrt{25y^2 +40y+16} = 5y + 4

\sqrt{(5y+4)^2} = 5y + 4

5y + 4 = 5y + 4 and 5y + 4 ≥ 0 ⇒ y ≥ - 0.8

y ∈ [ - 0.8 , ∞ )

- ( 5y + 4 ) = 5y + 4

10y = - 8

y = - 0.8

The answer is <em>y ≥ - 0.8</em>
