Answer 1

a) 100% ---------- R$ 300,00
10% ------------ x

x = 10*300/100
x = 3000/100
x = 30


b) 100% ---------- R$ 300,00
90% ------------ x
x = 90*300/100
x = 27000/100
x = 270


c) 100% ---------- R$ 300,00
110% ------------ x

x = 110*300/100
x = 33000/100
x = 330


d) 100% ----------- R$300,00
150% ------------ x

x = 150*300/100
x = 45000/100
x = 450


e) 100% ---------- R$300,00
200% ---------- x

x = 200*300/100
x = 60000/100
x = 600
