A student was given the single matrix equation [43−84][xy]=[2035]. The student wrote the equations as 4x+8y=20 and 3x+4y=35. Use the rule about matrix equations to identify the student's mistake. What is the error in the first equation? A The coefficient with y should be −8. B The coefficient with y should be 4. C The coefficient with x should be −4. D The coefficient with x should be 8

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

d.) 48 units
