Answer:
$3.61
Step-by-step explanation:
let p represent pizza and d represent drink, then
8p + 6d = 39.5 → (1)
5p + 7d = 30.44 → (2)
Multiplying (1) by 7 and (2) by - 6 and adding will eliminate d
56p + 42d = 276.5 → (3)
- 30p - 42d = - 182.64 → (4)
Add (3) and (4) term by term
(56p - 30p) + (42d- 42d) = (276.5 - 182.64), that is
26p = 93.86 ( divide both sides by 26 )
p = 3.61
That is a slice of pizza costs $3.61
