~asap offering 25 points will mark brainiest too~ question #1 don's fishing sells fishing lures for $1.88 after marking them up 380% based on cost. what is the cost of each lure to the nearest cent to don's fishing? question #2 a can of tennis balls has a 75% markup rate based on cost. mel's sporting goods sells a can of tennis balls for $3.49. what is the markup to the nearest cent? question #3 a can of tennis balls has a 75% markup rate based on cost. mel's sporting goods sells a can of tennis balls for $3.49. what is the markup to the nearest cent? a) $1.99 b) $2.00 c)$1.85 d)$1.84 question #5 a pair of earrings has a 130% markup rate based on cost. the selling price is $77.77. what is the markup to the nearest cent? (hint: find cost first.)

1. cost + 380%×cost = 4.80×cost = $1.88

... cost = $1.88/4.80 = $0.39

2. The relation between markup, cost, and selling price lets you find the cost, hence the markup.

... cost + markup = selling price

... cost + 0.75×cost = (1+0.75)×cost = 1.75×cost = $3.49

... cost = $3.49/1.75

... markup = 0.75×cost = 0.75×($3.49/1.75) = $3.49×(0.75/1.75) = $1.50

3. Same wording as 2. None of the given answers is correct.

... cost is $1.99; markup is 75%×$1.99 = $1.50; selling price = $1.99 + 1.50 = $3.49

(Have your teacher show you how to work this.)

5. Same as 2 and 3, but with different numbers.

... markup = (130%/230%)×(selling price) = (13/23)×$77.77 = $43.96

(Check: cost is 43.96/1.3 = 33.81; cost + markup = 33.81 + 43.96 = 77.77)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

i think that you should ask google for the answer to that problem because if we don't know it google does
