Hello!
Change each mixed number to an improper fraction to make it easier
2 3/8 = 19/8
5 3/4 = 23/4
Now, multiply
19/8 × 23/4 = 437/32 = 13 21/32
Answer ⇒ 13 21/32
Y = total cost
40 = The one time fee
90 = the service charge per month
x = number of months
If he goes there 4 times a week then $8 plus $2 equals $10 and times $10 by 4 times a week equals $40
So Elijah spends $40 a week at the restaurant
235.24 + 45.58 = 280.82
280.82/2 = 140.41
each check was for $140.41
