Tins of the brand of Sardines that I always buy are usually $1.75 each. Last week, however, they had been reduced to $1.08 each, so I took advantage of this and bought 48 tins. This week, they are back to $1.75 each, but, to my annoyance, there is a "buy 3 tins, get another 1 free" offer in place. How much more did I pay for the tins I bought last week than if I had bought them this week instead?

You actually saved 11.16 by buying them on the prevoius Shopping Trip.

Explanation:

1.08*48=51.84

1.75*3*12=63 (price per can 1.75*3/4=1.3125)

63-51.84=11.16

answer:

87 x 32= 2784

Explanation:

The result of  87 ⋅ 32

87  ⋅ 32

answer:

Rudy earned 63.5

Explanation:

So if all three friends earned 22 dollars and one got three times the amount of others he would have 66. 22×3 = 66. Then you would subtract 66-2.50= 63.5
