Question

Paige goes shopping and buys leggings for $24.95, a crewneck for $30.50, and a new purse (p). She says the expression 5.55+p can be used to find her total. Explain what she did wrong when writing her expression and write a new expression that correctly describes her total.

Answer 1

Answer:

$55.45+p$

The decimal point is one step behind and rounded the number.

Step-by-step explanation:

Cost of leggings = $24.95

Cost of crewneck = $30.50

Cost of new purse = p

The correct expression to find the total cost of her shopping is

$24.95+30.5+p$

$=55.45+p$

What Paige did was she put the decimal point one step behind and rounded the number.

$2.495+3.05+p$

$=5.545+p$

$=5.55+p$

So, she got the wrong expression.
