Question

In Mexico, avocados are 39 pesos per kilogram and the exchange rate is 9.7 pesos to the US dollar. What is the cost in dollars of an avocado that weighs 0.25 lb?

Answer 1

mass of avocados = 0.25 lb

Conversion factor for lb to kg is : 1 lb = 0.4536 kg

mass of avocados = 0.25 lb * (0.4536 kg / 1 lb)

mass of avocados = (0.25 * 0.4536) kg

mass of avocados = 0.1134 kg

Cost in pesos = (rate of avocados) * (mass of avocados)

Cost in pesos = (39 pesos/kg) * (0.1134 kg)

Cost in pesos = 4.4226 pesos

Conversion rate for pesos to dollars is : 9.7 pesos = $1

Cost in dollars = (Cost in pesos) * (Conversion rate)

Cost in dollars = (4.4226 pesos) * (1$ / 9.7 pesos)

Cost in dollars = $(4.4226 / 9.7)

Cost in dollars = $0.46
