Tito bought a rare album for $68.00 and later sold it for $76.00. what is the percent of increase, rounded to the nearest tenth?

the percent of increase is 11.8%

Step-by-step explanation:

Hello, I think I can help you with this

you can easily solve this by using a rule of three

if the prize tito paid is 100%, how many percent is $76?

if

$68.00 ⇒100%

$76.00 ⇒x%?

isolating x

so, $76.00 is 111.76 % of $68

the percent of increase will be the difference

111.76%-100%=11.76%=11.8%

the percent of increase is 11.8%

I hope it helps , Have a great day

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
