Answer 2

Part(A): The expression which represents the number of hours Matthew played soccer in a full week is
`5h + 6.5`

Part(B): the expression models her purchase is
`35.79-3b`.

Explanation:

Consider the provided information.

Part(A):

Matthew plays soccer for h hours per day for five days and he played a soccer tournament for a total of 6.5 hours.

So the required expression is:
`5h + 6.5`

Where 5h represents time spent in 5 days and 6.5 is the hours of the soccer tournament.

Part(B):

Mariah purchases three hair barrettes by using a gift card.

Let the cost of each barrette is b.

So the cost of 3 barrettes is:
`3b`

She uses a gift card with a balance of $35.79. Therefore subtract
`3b` from $35.79.

Her purchase can be expressed as:

`35.79-3b`

Hence, the required expression is
`35.79-3b`.
