Yoko needs 300 copies of her resume printed. Dakota printing charges 19.50$ for the first 200 copies and 9$ for every 100 additi
Leokris [45]

Answer:

A. c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

B. $29.78

Step-by-step explanation:

A. Based on the information given if we are to express the cost of the resumes which is c(r) algebraically as a piecewise function what we would have will be:

c(r)=$19.5 when r represent an INTERGER and is less than 2

c(r)=$19.5+(r-2) ($9) (1+0.045)

c(r)=$19.5+(r-2) ($9) (1.045) when r represent an INTERGER and is greater than 2

Therefore to express the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

B. Calculation for How much will 300 copies cost, including a sales tax of 4 1/2%

Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)

Cost of 300 copies=$28.5+$28.5(0.045)

Cost of 300 copies=$28.50+$1.28

Cost of 300 copies=$29.78

Therefore How much will 300 copies cost, including a sales tax of 4 1/2% will be $29.78

marshall27 [118]
-8(2a-3b)-5(6b)-5(-4a) \\ (-8*2a)+(-8*-3b)+(-5*6b)+(-5*-4a) \\ (-16a)+(24b)+(-30b)+(20a) \\ (20a-16a)+(24b-30b) \\ (4a)+(-6b) \\ 4a-6b
The answer is 4a-6b, which can also be written 2(2a-3b).

Hope this helps!

Pleaseeee helpppp !!!!!!!! Will mark Brianliest !!!!!!!!!!!!!

Answer:BE is equal to 72.

Step-by-step explanation: They are similar triangles. We know CD and BC. So we can find the comparison between the two. And we see that BC x 7 = CD. So the same will be said for BF and FE. We have BF is equal to 9. So 9 x 7 = 63. However, now we need to add the two together in order to get BE. Because BF + FE = BE. So 9 + 63 = 72
