Yuki888 [10]

Answer:

a) $14.37 sales tax

b) $25.13 left on gift card

Step-by-step explanation:

Purchases: 78.50 + 32.00 = 110.50

Sales tax: 13%:

1% of 110.50 = 1.1050

1.1050 x 13 = 14.365

rounded to 2 decimal places: $14.37

Total cost: 110.50 + 14.37 = $124.87

Gift card: 150.00 - 124.87 = 25.13

What’s the answer please help
noname [10]

Answer:

\boxed{\text{A. }\math{\left \{ x \, | \, x \in \mathbb{R}, x < -2 \right \}}}}

Step-by-step explanation:

The open circle means that the point is not included in the solution set, and the arrow pointing left means that all numbers less than -2 are members.

In set-builder notation, each term has a special meaning. The braces enclose the members of the set.

Here's how you translate the notation,

\begin{array}{rcl}\\\left \{ & = & \text{The set of}\\x & = & \text{all x values}\\| & = &\text{such that}\\x & = & x\\\in & = &\text{is a member of}\\\mathbb{R}, & = &\text{all real numbers, and}\\x < -2 & = & \text{x is less than -2}\\\end{array}\\\text{The answer is }\boxed{\textbf{A. }\mathbf{\left \{ x \, | \, x \in \mathbb{R}, x < -2 \right \} }}}
