Answer
The price of the shirt this year = $49.50
Step-by-step explanation
The shirt was $45.00 last year.
But it costs 10% higher this year.
The extra charge = 10% of $45.00 = 0.1 × $45 = $4.50
The price of the shirt this year
= (Price of the shirt last year) + (The 10% extra charge this year)
= $45 + $4.50
= $49.50
Hope this Helps!!!
