Sara has $50 in her wallet in $5 and $20 bills. Create a linear equation (with
77julia77 [94]

Answer:

<em>0 $20 bills and 10 $5 bills</em>

<em>1 $20 bills and 6 $5 bills</em>

<em>2 $20 bills and 2 $5 bills</em>

Step-by-step explanation:

<u>Equations</u>

Let's set:

x=number of $5 bills

y=number of $20 bills

The total amount Sara has is given by

5x+20y

And we know it's equal to $50, thus:

5x+20y=50

Dividing by 5

x+4y=10

We would need another condition to solve for x and y, but we can determine some combinations that solve the problem.

Solving for x:

x=10-4y

Since both x and y are integers and cannot be negative:

10-4y≥0

Swapping sides:

4y≤10

Dividing by 4:

y≤2.5

Thus, y can only have the values {0,1,2}

For y=0

x=10-4*0=10

x=10

For y=1

x=10-4*1=6

x=6

For y=2

x=10-4*2=2

x=2

Thus, the possible combinations are:

0 $20 bills and 10 $5 bills

1 $20 bills and 6 $5 bills

2 $20 bills and 2 $5 bills

The value of a bike depreciates by 55% per year. Work out the current value of a bike bought 2 years ago for £1300.
nikitadnepr [17]

Year 1: 1,300 * 55% = 715  depreciation
             1,300 - 715 = 585  book value

Year 2: 585 * 55% = 321.75 depreciation
             585 - 321.75 = 263.25 book value

Year 3: 263.25 * 55% = 144.79 depreciation
             263.25 - 144.79 = 118.46 book value

If the bike was bought 2 years ago, then its current value is $263.25. 

Currently, it is the beginning of Year 3 but depreciation is computed at the end of the year.
