16. Juke You bought 12 1-gallon bottles of apple and ochreous juice for a ground wanton. The apple juice was on sale for $1.00 per gallon bottle. The ochreous juice was $1.75 per 1-gallon bottle. You spent $15.00. Assign labels to the spoken copy under. Write an algebraic copy. How manifold bottles of each mold of juice did you buy?

17. Basesphere Outs. In a pastime, 18 of a basesphere team's 27 outs were fly spheres. Fifty percent of the outs made by infielders and 100% of the outs made by outfielders - were fly spheres. How manifold outs were made by infielders? How manifold.outs were made the equation for the calculate of fly sphere outs.)
