Mr. o'connor had $90 to spend at a football game. he spent 31/45 on his ticket. then, he spent 3/7 of his remaining money at the concession stand. while walking back to his seat, he saw a new hat on sale for $18. did mr. o'connor have enough money left to buy the hat? show all your work

He has $90 in total to spend

He spent (31/45) of this money on ticket

so money spent on ticket =(31/45) *90 =2790/45 =62

Now money left with him is 90-62 =28 $

Now it says that he spent (3/7) of this remaining money at concession stand

so money spent on concession stand =(3/7)*28 =84/7 =12

Now money left with him = 28-12 =16

So money left with him is $16 but hat costs for $18

So Mr. O'Connor didnt have enough moeny to buy the hat

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
