Answer:
Michael bought 8 shirts
Step-by-step explanation:
Let the number of shirts to be buy be x
The number of ties too will also be x
The number of pants will be x/4 since he will be buying four times the number of pants for shirts
Amount spent on shirt is 35 * x = $35x
Amount spent on ties = 25 * x = $25x
Amount spent on pants = 40 * x/4 = $10x
Adding all together;
35x + 25x + 10x = 560
70x = 560
x = 560/70
x = 8
