Answer:
Step-by-step explanation:
Semester Costs = 8*2858 =                     22864
Books / semester= 8 * 391 =                        <u>3128</u>
Total                                                            25992
If he wants to repay all this in six years the answer would be
45000 + 25992/6 = 45000 + 4332 = 49332
 
        
             
        
        
        
Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2 
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
