the answer would be 2(4.75x)
EXPLANATION:
He is getting both his brother and sister truffles which the 2 represents.
The 1.75 is the cost per truffle
he gets them gift wrapped so you add the total of each costing truffle 1.75 + 3.00= 4.75
but doesn’t know the amount he will be getting which the X represents.
which gives you the equation of 2(4.75x)
