Answer:
I don't understand percentages
Let the number be y
The statement can be interpreted as
85% of y = 646
Answer:
80 pounds.
Step-by-step explanation:
Let W₁ be the initial weight of water in the grapefruit, W₂ be the weight of water in the grapefruit after evaporation, and M be the total weight of the grapefruit after evaporation. Assuming that, originally, the grapefruit weighed 100 pounds with a 92% water content and the weight of the "non-water" part of the fruit (100 - W₁) does not change. The final weight of the grapefruit (M) is given by:

The grapefruit now weighs 80 pounds.
123x - 23(-1 + x) = 14
Simplify.
123x + 23 - 23x = 14
Subtract 23 from both sides.
123x - 23x = 14 - 23
Simplify.
100x = - 9
Divide both sides by 100.
x = -9/100
