Answer:
In total she works 21 hours and for the equation its gn=g+n
Step-by-step explanation:
got the equation i just put gn but that can be replaced with 21 since g and n both represent the number of hours fawzia works
Let x represent invested money at 9% and y at 7%
Now we write system:
x+y = 6300
1.09*x + 1.07* y = 6300 + 493 = 6793
1.09x + 1.09y = 6867
Here we multiplied first equation with 1.09 and now we will subtract second from first:
0.02y = 74
y = 3700
x = 6300-3700 = 2600
Michael invested 2600 at 9% and 3700 at 7%
80% of 10% = 0.8 x 10% = 8%
If you calculate 20-3.58 the answer is $16.42
The only reasonable answer is 16. The other 2 possible answers (8 and 24) do not make sense. 24 is a multiple of 8, but 23 is not a multiple of 5. 8 is a multiple of 8 but 7 is not a multiple of 5.
