Price of each enchalida is #$2.90#, but each taco reduces it by #$0.60#.

Explanation:

As friend had ordered one taco and two enchalida more than me and has paid #$12.70-7.50=$5.20# more, this is the price of one taco and two enchalida.

Hence doubling two tacos and four enchalida cost #2×5.20=$10.40#. But two tacos and three enchalida cost #7.50#. Hence price of one enchalida is #$10.40-$7.50=$2.90#.

This means three enchalida cost #$2.90×3=$8.70# and as total price paid by me was just #$7.50#, reduction in price for two tacos is #$8.70-$7.50=$1.20# and price of one taco must be #$-1.20÷2=$-0.60# i.e. price of each taco is reduced by #$0.60#.

Checking it for friend fivee enchalida cost #$2.90×5=$14.50# which is reduced by price of three tacos i.e. #$0.60×3=$1.80# and total price is #$14.50-1.80=$12.70#.
