Monica paid sales tax of $2.80 when she bought a new bike helmet. If the sales tax rate was 7%, how much did the store charge fo

larisa [96]

7 % of cost price is 2.80 , What about 1%?

7 = 2.80

1 = x (where x is the price value of 1% in dollars)

We simplify the above equation, so:

7 × x = 2.8 × 1 → 7x = 2.8 → x = 2.8 / 7 → x = 0.4 dollars

We know that 100% represents the whole price,

so if 1% is 0.4 dollars, then 100% will be 0.4 × 100 = 40 dollars

Therefore the store charged $40 dollars for the helmet before tax

How do you solve for Y in x=5 +8y-8

Rzqust [24]

x = 5 + 8y - 8

Combine like terms.

x = -3 + 8y

Add 3 to both sides.

x + 3 = 8y

Divide both sides by 8.

y = $\frac{x+3}{8}$

Write the equation 2x - 3y = 6 in slope-intercept form.

ExtremeBDS [4]

Answer:

$y = \frac{ 2}{ 3} x - 2$

Step-by-step explanation:

$2x - 3y = 6 \\ - 3y = - 2x + 6 \\ \\ y = \frac{ - 2}{ - 3} x + \frac{6}{ - 3} \\ \\ \huge \purple{ \boxed{ y = \frac{ 2}{ 3} x - 2}} \\ this \: is \: in \: the \: slope - intercept \: form.$
