After 25% of a bill is paid $80 still remains to be paid. how much was the bill?

Answers

the original bill was valued at 106.67 $

if 25% was paid, and 80 dollars are left, this means that 80 dollars is 75% of the bill. 25% is a quater, and 75% is three quarters.

here, we can divide 80 into three parts ->

80 ÷ 3 ≈ 26.67
that means a quater of the bill is 26.67 $

if 80$ were left to be paid, just add the 26.67$ from the first quater ->

80 + 26.67 = 106.67 $

Ms. Leong owned an ice cream store and had chocolate and vanilla ice cream for sale. She sold 3/4 of the chocolate ice cream and 1/2 of the vanilla ice cream. If she had 20 scoops of chocolate ice cream and 30 scoops of vanilla ice cream left, how many scoops of ice cream did Ms. Leong have altogether at first?

Answers

Answer: 140 scoops.

Step-by-step explanation:

We know that she sold 3/4 of the chocolate ice cream and 1/2 of the vanilla ice cream. She originally had 20 scoops of chocolate and 30 of vanilla left.

so those 20 scoops of chocolate are 1/4 of the total amount that she had before, then the total amount is equal to 4 times 20 scoops = 80 scoops of chocolate.

We also know that 30 scoops of vanilla are one half of the initial number, so the initial number must be equal to two times 30 scoops = 60 scoops.

Now, adding those numbers we have 60 + 80 = 140 scoops in total at the beginning of the day.

The answer is 140 scoops of ice cream total .

Answers

434.657, hundredth digit is 5, after the 5 is 7, since the 7 is more than 5, we add 1 to the hundredth digit 5, to make it become 6.

434.657 ≈ 434.66 to the nearest hundreth.

102.494, hundredth digit is 9, after the 9 is 4, since the 4 is less than 5, we the hundredth digit remains as 9.

102.494 ≈ 102.49 to the nearest hundreth.
