Answer:

15, 17, 19

Step-by-step explanation:

let the first odd number be n then the next 2 are n + 2 and n + 4 , then

n + n + 2 + n + 4 = 51

3n + 6 = 51 ( subtract 6 from both sides )

3n = 45 ( divide both sides by 3 )

n = 15

Then

n + 2 = 17 and n + 4 = 19

The 3 consecutive odd numbers are 15, 17, 19

Morgan’s grandmother orders her groceries online and has them delivered to her house. Her bill is $120. She has a coupon for 20%

iragen [17]

Answer:

The total price of the groceries, including discount and tip is $110.4.

Step-by-step explanation:

Here, the bill amount of groceries = $120

Now, the coupon off = 20%

Calculating the discount, we get

20% of bill amount $120 = 20% of 120 = $\frac{20}{100} \times 120 = 24$

So, the 20% discount on the bill amount = $24

The actual payable amount = Bill Amount - Discount

= $120 - $24 = $96

Now, 15% tip is also applied on the actual payable amount $96.

15% of 96 = $\frac{15}{100} \times 96 = 14.4$

So, the total price t = Payable amount + Tip amount

= $96 + $14.4 = $110.4

or, t = $110.4

Hence, the total price of the groceries, including the discount and the tip is t = $110.4.
