Answer:
<u>Let x the the number of cans of tomatoes and </u>
<u> 32 - x be the number of cans of corn</u>
From the given that the total cost in buying all 32 cans of vegetables is $18 and the costs of each can of vegetables, we generate the equation,
18 = 0.80x + 0.40(32 - x)
Solving for x from the equation gives x = 13. Alex bought 32 - x cans of corn with a numerical value of 19. Thus, Alex bought<em><u> 19 cans of corn</u></em>.
