DAX to return the max value for each customer

[BenHoward]

I have a table with the following type of data

Customer	Value
A	10
B	20
C	15
A	10
B	21
B	15

I  want to display a table in Power BI which just displays the max value for each customer, eg

Customer	Value
A	10
C	15
B	21

I then need another measure which totals the max (to display in a card), so that value in the above example would be 46.

Can anyone help with the dax measures please?

Max w Total = 
SUMX ( 
    VALUES ( Ben[Customer] ),
    CALCULATE ( MAX ( Ben[Value] ) )
)
