Answer:
Laptop = $3250
Desktop = $2900
Step-by-step explanation:
Total finance charge = $398
Laptop cost = 350 + x
Desktop = X
Workings
Finance cost = (7% *X ) + (6% * 350+x ) = 398
0,07 X + 0.06 X + 21 = 398
0.13 X + 21 = 398
0.13 X = 398 -21
0.13 X = 377
Therefore ,X = 377/0.13
=2900
Cost of Desktop = 2900
Cost of Laptop =2900+350 =3,250
