Chris made one error as she found the value of this expression.
2(-20) + 3[5/4 (-20)] +5[2/5(50)] + 4(50)
step 1: 2(-20) + 3(-25) + 5(20) + 4(50)
step 2: (3 + + -25) + (5 + 4)(20+50)
step 3: 5(-45) + 9(70)
step 4: -225 + 630
step 5: 405
identify the step in which chris made her first error. after identifying the step with the first error, write the corrected steps and find the final answer.
can someone me with this problem. it would mean a lot.
