Barbra bought 2 greetings cards at $1.50 each, 3 packages of wrapping paper at $2.29 each and 1 roll of ribbon for $1.45. How much did she spend altogether?

$11.32

Step-by-step explanation:

Greeting Cards = $1.5 x 2 = $3

Wrapping Paper = $2.29 x 3 =  $6.87

Ribbon = $1.45 x 1 = $1.45

So now we must add the totals to figure out how much money Barbra spent in total.

$3 + $6.87 + $1.45 = $11.32

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
