You are buying a pair of sneakers for $ 120. You have a coupon to save 45 %. How much will the sneakers cost ?

$66

Step-by-step explanation:

100 - 45 = 55 ⇒ 55 ÷ 100 = 0.55

→ Multiply the multiplier by the price

0.55 × 120 = $66

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
