4:1
(grapes);(rasins)
4:1
x:3000
so you then cross multiply
1·x=4·3000
multiply,
x=12000
so the answer is it takes 12000 pounds of grapes to make 3000 pounds of raisins

<span>241 of the 25¢ notebook
107 of the 38¢ notebook
1) Let x = no. of 25¢ notebooks sold and y = no. of 38¢ notebooks sold
2) Total notebooks sold: x + y = 348
3) Revenue from the notebooks: 0.25x + 0.38y = 100.91
4) Substitute one equation to the other and solve for a single variable (either x or y)</span>
