Answer:
x=16
Step-by-step explanation:
9 times 4 is $36 which is the price of the belt
$36 + $9 = 45
$45 + $ 10 = 55 so
<u>Keith had $55 dollars before he bought the shirt and the belt
</u>
If you knew that 8*300=2400
Then you could likely figure that 8*20=160
And then just add the two together to get 2560
