Answer:
he invested $10,000 at 7% and $12,000 at 6%
Step-by-step explanation:
- There are 2 equations that appear from this problem
- X+Y=22,000 and 0.07x + 0.06y = 1420
- Lets start by simplifying X+Y=22000
Y = 22000 - x
- now plug this into the Y value for the other equation
0.07x + 0.06(22000-x) = 1420
0.07x + 1320 -0.06x = 1420
0.01x = 100
X = 10000
- now plug 10000 into x for the simplified equation
Y = 22000 - 10000
Y = 12000
Is this how it wrote the discount? Because if so, it would be 7% off of the original price. Then you'd get a grand total and answer of:
$1116.00
The discount of 15% is $149.25 ,you now only have to pay $845.75.
Well, i think you just need to move the 2 matches on the top and the bottom of the number 0 and put it after the number 8
This way, you will change the number from
5 0 8
into
5 1 1 8 1 1
hope this helps
