Let x = the number of fat grams in the apple
Let y = the number of fat grams in the cup of cottage cheese
x + y = 4.03g
x = 1/30y
Substitute 1/30y for x in the equation:
1/30y + y = 4.03g
Simplify:
y + 30/30y = 4.03g
Multiply both sides by 30:
30y + 30/30y = 120.9g
Simplify:
30y + 1 = 120.9g
Subtract 1 from both sides:
30y = 119.9g
Divide both sides by 30:
y = 3.997g
Substitute 3.997g for y in the equation x = 1/30y:
x = 1/30(3.997g)
Simplify:
x = 0.133g
Therefore, the apple contributes 0.133g of fat and the cup of cottage cheese contributes 3.997g of fat.
An apple in a dessert contributes one-thirtieth the number of fat grams that the cup of cottage cheese contributes. If the total number of fat grams in the dessert is 4.03g, how many fat grams are in the apple and how many are in the cup of cottage cheese?
