4.6=e-3.2 plz i’m kinda confused here

Two blends of tea are mixed to make a blend that will be sold at the fair. black tea sells for $2.20 per pound and orange pekoe tea sells for $3.00 per pound. how much of each should be used to obtain a 4lb blend selling for $2.50 per pound?

Which of these triangle pairs can be mapped to each other using a single translation? cof hn
