Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items wit

weeeeeb [17]

Answer:

$Change = \$8.82$

Step-by-step explanation:

Given

$Basketball = \$25.57$

$Air\ Pump = \$15.61$

$Amount = \$50$

Required

Determine the change received

First, we need to calculate the total amount spent

$Total = \$25.57 + \$15.61$

$Total = \$41.18$

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

$Change = Amount - Total$

$Change = \$50 - \$41.18$

$Change = \$8.82$

<em>Hence, the change is $8.82</em>
