Let x be the amount invested at 7% and y the amount invested at 6%
We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500

The six dollars for eight ounces is the cheaper one.
you have to find the common denominator between 5 and 8, the simplest I thought of was forty so to get the eight to forty, you multiply by five and six times five equals thirty and you do the same for the other one except it's times eight for this one so it'll equal thirty two, so there isn't much difference (two) but the first bottle has the lower unit rate
