Answer: Sandra's salary in the previous year was $48,000
Step-by-step explanation:
Hi, the expression given is missing the $2000 more that she earns this year.
0.14 (x +2000) =7000
Where:
- <em>x is Sandra's salary in the previous year.
</em>
- <em>0.14 is the decimal form of 14% (14/100=0.14)
</em>
Solving for x :
0.14(x) +0.14 (2000) =7000
0.14x +280 =7000
0.14 x = 7000-280
0.14x = 6720
x = 6720/0.14
x=48,000
Sandra's salary in the previous year was $48,000
Feel free to ask for more if needed or if you did not understand something.
Step-by-step explanation:
x = number of $50 bills
y = number of $100 bills
x + y = 20
50x + 100y + 500 = 100x + 50y
50y + 500 = 50x
y + 10 = x
now we use that in the first equation :
y + 10 + y = 20
2y = 10
y = 5
x = y + 10 = 5 + 10 = 15
so, he has 15 $50 bills and 5 $100 bills = $750 + $500 = $1250 in his wallet
