I think below is your full question:
<em>Erin and Dan went shopping at their local store. Erin bought shirts that cost $12 each and spent $18 on accessories. Dan bought the same number of shirts as Erin for $16 each and spent $10 on accessories.
</em>
<em>If Erin and Dan were billed the same amount by the store, how many shirts did each of them buy?</em>
Here is my answer
Let x is number of shirts
Person COST
ERIN 12x+18
DAN 16x+10
Equally Billed 12x+18=16x+10 <=> x = 2
so each of them buy 2 shirts

Step-by-step explanation:
The hydronium ion is H₃O⁺ and its concentration is equivalent to the H⁺ ion concentration. The H⁺ ion concentration is given by:
pH = -log[H⁺]
[H⁺] = 10^(-8.2)
[H⁺] = 6.31 x 10⁻⁹ mole/dm³
The hydronium ion concentration is 6.31 x 10⁻⁹ mole/dm³
