Today, everything at a store is on sale. The store offers a 18% discount. a. The regular price of a T-shirt is $20. What is the discount price?

Discount : 3.60$

Discounted shirt price: 16.40$

Step-by-step explanation:

If there is a 18% then we can get the discounted price you get by multiplying 20$ by 18%

So we can change 18% to decimal if we need to by just moving a decimal point 2 decimal points to the left. so .18.

Now 20*.18 = 3.60$ | That is the discount you get on sale. To get the actual discount price you just need to subtract 20-3.6=  16.40$

Step-by-step explanation:

To calculate the 18% discount, convert 18% into the equivalent decimal fraction 0.18 and then multiply the regular price ($20) by 0.18; the discount is thus $3.60.

Subtract the discount, $3.60, from the regular price ($20) to obtain the discount price:  $16.40.

Alternatively, take the shortcut of multiplying $20 by (1.00 - 0.18), or

$20 by 0.82.  The result (i. e., the discount price) is the same:  $16.40

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
