find 30 potatoes at the x-axis and look at where the line is at
The shapes are similar.
When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Therefore,

Simplify:

Cross multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 57x - 42x
420 = 15x
x = (420÷15)
x = 28
PLUG in the numbers
4.5=500 x R x 2.5
divide both sides by 500
0.009=R x 2.5
divide 2.2 to both sides
R=.0036
In percent you have to multiply by 100 which is 0.36%
