Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
5 times 40 times 49 equals 9800 because you do 5 time 4 and that's 20 and you add a 0 and you multiply by 49 to get 9800.
Y=3x
y=2x+5
Then solve with substitution:
3x=2x+5
x=5
$1.45
1.50 times .05= 0.075
the sales tax was 0.075 cents, so if you subtract that from $1.50, you get the price before sales tax
