At the supermarket, limes are sold for $5.00 per bag and grapefruits for $12.50 per box. A bag contains 6 limes and a box contains 15 grapefruits. Only a whole number of bags and a whole number of boxes can be purchased. Part A: On Thursday, a chef purchased 12 bags of limes and some boxes of grapefruits. If the total cost was $135.00, how many boxes of grapefruits were purchased? Part B: On Sundays only, there is a 20% discount on the price of a bag of limes and a 15% discount on the price of a box of grapefruits. What is the total cost for 4 bags of limes and 8 boxes of grapefruits? Part C: On Tuesday, the chef needed 80 limes and 50 grapefruits. The chef purchased just enough bags and boxes. Determine how much the purchase cost her. Part D: On Wednesday, the chef made tarts that each required 1 lime and 2 grapefruits. If the chef spent exactly $75 total on limes and grapefruit, determine the greatest number of tarts she could have made?

did you get the answer yet?

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
