Question

carlos has made 4 purchases from an online store. at the store, each purchase earns 2.4 points (called reward points). (a) let n be the total number of points carlos has earned. write an equation that can be used to find n. first choose an appropriate form. then fill in the blanks with the letter n and the numbers 4 and 2.4. \\(\square + \square = \square\\) \\(\square - \square = \square\\) \\(\square \times \square = \square\\) \\(\square \div \square = \square\\) (b) solve your equation for n to find the total number of points carlos has earned.

Explanation:

Part (a)

Step1: Identify the operation

Carlos makes 4 purchases, each earning 2.4 points. To find total points, we multiply the number of purchases by points per purchase. So the operation is multiplication.

Step2: Form the equation

Using the multiplication form \(\square\times\square=\square\), we substitute the number of purchases (4), points per purchase (2.4), and total points (\(n\)). So the equation is \(4\times2.4 = n\) (or \(2.4\times4=n\)).

Part (b)

Step1: Calculate the product

To solve \(n = 4\times2.4\) (or \(n = 2.4\times4\)), we multiply 4 and 2.4.
\(4\times2.4=9.6\)

Answer:

(a): \(4\times2.4 = n\) (or \(2.4\times4 = n\))
