Question

Cem bombons custam R$ 37,0. Qual é o preço de 150 bombons ? E de 210?
Quando bombons se pode comprar com R$ 92,50 ?

Answer 1

10 custam R$3,70 
150 = 3,7×15 = R$55,50
210 = 3,7×21= R$77,70
R$92,50÷R$3,70 = 25 bombons

Answer 2

100 bombons = 37.00
1 bombom = 0.37
10 bombons = 3.70
50 bombons = 18.50

150 bombons = 100 bombons + 50 bombons
                           37 + 18.50 = 55.50
210 bombons = 100 bombons + 100 bombons + 10 bombons
                           37 + 37 + 3.70 = 77.70

92.50 / 0.37 = 250 bombons

37 / 100 = 0.37
0.37 * 10 = 3.70
0.37 * 50 = 18.50

Resposta: {55.50; 77.70; 250 bombons}
