Answer:
<h3> Let's start with the total money needed for basketballs</h3>The total money the coach will need for 40 basketballs will be 40 times price of one basketball.
Thus we need to find the price of one basketball.
$27 for 3 basketballs
Thus for one basketball, Which gives us,
'9'.
So for 40 basketballs 40 * $9
Which gives us $360.
<h3>Now let's find the total money needed for sneakers.</h3><h3></h3>The total money needed for sneakers is 7 times the cost of one sneaker.
So, we need to find the cost of 1 sneaker
which is which gives us,
$18.
Thus total amount of money needed for sneakers is 9 * $18 which gives us
$162
So total amount the coach has to pay is $360+$162 <em>(total cost of basketballs + total cost of sneakers)</em>
=$552
Therefore, total amount the coach has to pay is $552
