Cans of black beans usually cost $1.34 each. This week they are on sale for 5 cans for $6.00. You bought one can last week and one can this week. How much more or less did you pay this week?

Answer 1

Answer:

$0.14 less to pay this week.

Step-by-step explanation:

Given:

Cans of black beans usually cost $1.34 each.

This week they are on sale for 5 cans for $6.00.

You bought one can last week and one can this week.

Now, to find the amount more or less to pay this week.

So, we use unitary method to get the price of can this week:

If, 5 cans cost this week = $6.00.

Then, 1 can cost this week = $\frac{6}{5}=\ 1.20.$

Thus, the cans of black beans cost $1.20 this week.

And, last week the cans cost $1.34 each.

So, the cost of can this week is less than last week.

Now, we get the difference in the cost of can of this week than last week by subtracting the cost of can last week from cost of can last week:

$\ 1.34-\ 1.20\\\\=\ 0.14.$

Therefore, $0.14 less to pay this week.
