3%?? The question doesn't make much sense.
first you do 7100 times 10=71,000
<span><u><em>The correct answer is: </em></u>
535.
<u><em>Explanation</em></u><span><u><em>: </em></u>
4 hundreds = 4*100=400.
13 tens = 13*10 = 130.
5 ones = 5*1=5.
Together, this gives us 400+130+5=535.</span></span>
To solve this equation, we will need to isolate y, the variable. These are the steps that follow:
1. Add 0.3y to each side.
2. Subtract 21.3 from each side.
3. Divide both sides by 5.4y.
Try and figure it out yourself! If you have trouble...
The answer is y = -8.5
55 + 8.50d = 123
55 for rental
8.50d for each day she pays 8.50 so add the d and then equal sign and 123.
