Answer:

taco = $1.15

small glass of milk = $0.95

Step-by-step explanation:

t = taco

m = small glass of milk

t + m = $2.10

2t + 3m = $5.15

(2t + 3m) - (t + m) = t + 2m

$5.15 - $2.10 = $3.05

t + 2m = $3.05

(t + 2m) - (t + m) = m

$3.05 - $2.10 = $0.95

m = $0.95

t + $0.95 = $2.10

$2.10 - $0.95 = £1.15

t = $1.15
