Mrs. Carter owns a shop specializing in obscure blends of tea. She has combined 1 pound of Darjeeling with 3 pounds of Earl Grey, for a 4-pound mixture that is 25% Darjeeling. After tasting it, she decided to change the mixture to 50% Darjeeling. How much Darjeeling does she need to add to bring it up to the 50%?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

Iwould say 48 bc the line of x is the line of 6 so 6×6=48
