$7.50

Step-by-step explanation:

2 hambugers cost $2.50*2 = $5.00

1 Fries = $1.50

1Soda = $1.00

Total cost = $5.00 + $1.50 + $1.00 = $7.50

Cost of one Hamburger = $2.50

Cost of a packet of Fries = $1.50

Cost of one Soda = $1.00

Total cost = The sum of his meal

Total cost = $ [ 2(2.50) + 1.50 + 1.00 ]

Total cost = $ ( 5.00 + 1.50 + 1.00 )

Total cost = $ 7.50

The total cost of his meal was $7.50 .
