The width of the river = 60m and so Zachary will be able to swim the river without getting tired.
<h3>What is Proportion ?</h3>
When two ratios are equal , the ratio are said to be in proportion.
As given in the question ,
the width of the river has to be determined
Looking at the figure , the triangle formed at the side of the river is a right triangle the hypotenuse will be determined from the Pythagoras theorem
20² +24² = y²
y = 21.2 m
As the corresponding sides are proportional
31.2 : z = 20:50
z = 78.1
The value of the width of the river will be determined by the Pythagoras Theorem
78.1² = 50² + x²
x = 60m
the width of the river = 60m
Therefore Zachary will be able to swim the river without getting tired.

Step-by-step explanation:
Let x be the money made in sales. Let y be the money made in commissions.
First, convert 2.5% to a decimal.
2.5% = 0.025
Equation:
0.025x = y
Robert:
0.025(8850) = y
y = $221.25
Francisca:
0.025x = 279
x = 279/0.025
x = $11,160
Manufacturing cost = $136
sellers added 25% = $ 136 * 25/100 = $34
manufacturers cost + 25% = $136 + $34 = $170.
old selling price = $170
Sellers decreased the markup to 17% (of manufacturing cost): $136 x 17/100 = $23.12
New selling price = $136 + $23.12 = $153.12
both of these answers show: original cost + markup value
Answer:
ok that is correct because you start with 25 and then add 9 each week so 25+9w
