The Italian government decides to stimulate the economy by sending checks worth $70 billion to Italian consumers. If the (government spending) multiplier is 1.5, calculate the MPC to determine the final change in Italy's real GDP due to the transfer? Please give your answer as a whole number in billions of dollars.
$35 billion
($70 billion)(1.5) = $105 billion
$105 - $70 billion = $35 billion
