First find the increase
45 * 35%
45*.35
15.75
Add this to your sales
45+15.75
60.75
Since you cannot have part of a sale, round up

The distance Terry needs to run when the winner crosses the finish line is 1. 6 miles.
<h3>How to find the distance Terry needs to run?</h3>
The race was a 10 km race and she has completed 74% of the race when the winner crosses the finish line.
Therefore, the number of more miles Terry need to cover can be calculated as follows:
74 / 100 × 10 = 740 / 100 = 7.4 km
He has covered 7.4 km.
The distance remaining to cover = 10 km - 7.4 km = 2.6 km
Therefore,
4km = 2.48 miles
2.6 km = ?
cross multiply
The distance remaining to cover(miles) = 2.6 × 2.48 / 4
The distance remaining to cover(miles) = 6.448 / 4
The distance remaining to cover(miles) = 1.612
The distance remaining to cover(miles) = 1.6 miles

Step-by-step explanation:
<u>Step 1: Define</u>
5 - 7(2 - x) = 31 - 4(2x - 5)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5 - 14 + 7x = 31 - 8x + 20
- Subtract/Add: -9 + 7x = -8x + 51
- Add 8x on both sides: -9 + 15x = 51
- Add 9 to both sides: 15x = 60
- Divide 15 on both sides: x = 4
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 5 - 7(2 - 4) = 31 - 4(2(4) - 5)
- (Parenthesis) Multiply: 5 - 7(2 - 4) = 31 - 4(8 - 5)
- (Parenthesis) Subtract: 5 - 7(-2) = 31 - 4(3)
- Multiply: 5 + 14 = 31 - 12
- Add/Subtract: 19 = 19
Here we see that 19 does indeed equal 19.
∴ x = 4 is the solution to the equation.
