Kymari wants to buy soup. She knows that 5 cans of chicken noodle soup are going for $10. The store also offers 3 cans of tomato soup for $9. If she wants to buy 16 cans of chicken noodle and 11 cans of tomato, how much will she spend in total? Remember to include units.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
