The regular price of a T-shirt is $18 and has a 20% off tag what is the discount price

$14.40

Step-by-step explanation:

Because it is 20% off, the price of the T-shirt will be 80% of the regular cost. Multiply 18*.8 to get the answer of $14.40

I think this is the   $3.6

Step-by-step explanation:

$18 > 100%

$9 > 50%

$4.5 ---> 25%

$3.6 --→ 20%

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
