(a) How much money, in dollars, in terms of x and y, did Allan spend altogether?​

$4.25

Step-by-step explanation:

x pens=$1.75

y pens =$2.50

Now,

in the terms of x and y ,

Alan spend altogether=1.75 +2.50

=$4.25

$53.50

step-by-step explanation:

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

the correct answer is $7.38
