Daljit has has $1500 and she invested it in some stocks. In one day, her money was doubled. The following day she lost $700. On the third day, her investments tripled in value. Write the correct BEDMAS expression for this, then solve to figure out how much money Daljit has. Show your work.

(1500 x 2 - 700) x 3

=(3000 - 700) x 3

= 2300 x 3

= 6900. 

Daljit has $6900

Amrit has $450. He spends $210 on food. He then divides the remaining money into four parts. At home, he searches through his belongings and finds a stack of ten 5-dollar bills. Write the correct expression to represent how much money Amrit has, and solve. Show all your work.

(450 - 210) ÷ 4 + 10 x 5

= 240 ÷ 4 + 10 x 5

= 60 + 10 x 5

= 60 + 50

= 110. Amrit has $110
