Asalsa recipe uses green pepper, onion, and tomato in the extended ratio 3: 5: 7. how many cups of tomato are needed to make 105 cups of salsa?
a. 7
b. 21
c. 35
d. 49

To find the answer, we can first find out the proportion of tomato in a cup of salsa in percentage:

7/3+5+7
=7/15

We can then proceed to find the cups of tomato needed in 105 cups of salsa by multiplying the proportion to 105:

7/15×105
=7/5x3 × (5×21)
=7/3 x (3×7)
=7x7
=49

Therefore,49 cups are needed.

Hope it helps!
