I have three questions that I cannot figure out how to do? Please help if you can and show all work!
1. Marianne spent twp-fifths of her salary on a scarf and a hat. The hat costs three times as much as the scarf. If she has $36.00 left, how much did the scarf cost?
2.Mr. Jacobs gets a monthly statement on his investments from his financial advisor. The change in the value of his investments for the last six months was: -$327.50, -$98.85, -$63.77, -$ 38.23, +$22.97. Estimate the net change over the last six months.
3.Estimate each situation. Explain your reasoning.
A
What number(s) greater than 0 can you multiply 3.2 by to make the product less than 3.2, greater than 3.2 or equal to 3.2? Justify your answers.
B What number(s) less than 0 can you multiply 1/2 by to make the product less than 1/2, greater than 1/2, or equal to 1/2? Justify your answers.
Please help fast! Thanks
