Mrs boyle buys 2g pounds of beef, mrs anand buys 1.5 pounds less than mrs boyle, if mrs anand buys d pounds of beef, express d in terms of g

Mrs. Boyle: 2g pounds of beef
Mrs. Anand: 1.5 pounds less that that bought by Mrs. Boyle = 2g-1.5
However, the amount of beef bought by Mrs. Anand is equivalent to "d"
Therefore,

d=2g-1.5
