Given - -

1 pound = $ 1.68

Calculations

To find how much 4 pounds cost multiply by 4.

To find. 5 divide 1.68 by 2 and add it to 6.72.

1.68 : 2 = 0.84

6.72 + 0.84 = 7.56

She spent $ 7.56

We just need to multiply the amount of pounds and the cost of each one of them, that is:

spent = 4.5*1.68
