Can someone help with me this question?

1. Lea spent $25 of the money she saved. She still has 60% of her money left. How much does have left?

0.60 x 25=$15?

2. A 2.6L container of juice costs $3.00. How much are you paying for 1 L?

Having spent $25, LEa realizes that she still has 60% of her original sum.

Therefore, $25 must represent 40% or her original sum making the original sum 25/.40 = $62.50.

$62.50 - $25.00 = $37.50.

$37.50/$62.50 = .6 or 60%.

$3.00/2.6 = $1.15 per liter

Suppose the ratio of the number of boys to the number of girls in a class is 7:3. What percent of the class is girls?

To find out how much you are paying for 1 L of juice, you need to divide the cost of the 2.6L container by its volume in liters.

Step 1: Calculate the cost per liter.
Cost of 2.6L container = $3.00
Cost per liter = $3.00 / 2.6 L = $1.15 (rounded to the nearest cent)

Therefore, you are paying $1.15 for 1 L of juice.

To find out how much you are paying for 1 liter of juice, you need to divide the total cost of the 2.6L container by the number of liters.

Step 1: Calculate the cost per liter by dividing the total cost ($3.00) by the number of liters (2.6L).

$3.00 รท 2.6L = $1.15 per liter

Therefore, you would be paying $1.15 for 1 liter of juice.
