Write a word problem about Raffaele, Valery, and Leon using this expression
20% of R = 30% of V,
20/100R = 30/100V
1/3R = 3/10V
Make the numerators the same,
3/15R = 3/10V
Therefore,
R: 15u
V: 10u
V is 80% of L,
80%L = 10u
20%L = 10u/4 = 25u
100%L = 2.5u * 5 = 12.5u
a)
R:V:L = 15 : 10 : 12.5
R:V:L = 30 : 20 : 25
R:V:L = 6 : 4 : 5
b)
V = 10u
L = 12.5u
10u + 650
2.5u = 650
1u = 650/2.5 = 260
15u = 15 * 12 = $3900
