Expand can mean "To stretch or unfold." How can this definition help you remember this definition
mihalych1998 [28]
<span>There are several examples that can help one remember the definition of expand. To begin with, a balloon can expand when air or water enters it, depending on the type. Cookies often expand when baking due to the leavening agent used in the recipe. When we stretch our bodies, our muscles often expand.</span>

Mrs. Gonzales has only $63.50 to spend at a clothing store. She wants to buy a shirt that costs $28, including tax, and some bra
ehidna [41]

Answer:

Mrs. Gonzales can buy a maximum of 7 bracelets.

Step-by-step explanation:

A shirt costs $28 total.

Bracelets cost $4.50 each total.

Mrs. Gonzales has $63.50 in all, assuming she wants to spend all of it.

Set the equation, let bracelets be denoted by the variable, x.

4.50x + 28 = 63.50

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 28 from both sides:

4.50x + 28 (-28) = 63.50 (-28)

4.50x = 63.50 - 28

4.50x = 35.50

Next, divide 4.50 from both sides of the equation:

(4.50x)/4.50 = (35.50)/4.50

x = 35.50/4.50

x = ~7.89

However, note that you cannot round up, as you are buying. You also cannot buy .89 of a bracelet, so round down.

x = 7

Mrs. Gonzales can buy a maximum of 7 bracelets.
