Program Code to Copy:

clc,clear,close all

fileID = fopen('parts_inv.dat','r');
formatSpec = '%d %f %f'; % format of one line of data
sizeA = [3 Inf]; %
inventoryData = fscanf(fileID,formatSpec,sizeA);
fclose(fileID);

totalDollarPerPart = inventoryData(2,:) .* inventoryData(3,:); % cost*quantity
totalDollar = sum(totalDollarPerPart)
