salad dressing is made by mixing lemon juice and olive oul in the ratio 2:5 by volume. the cost of lemon juice is $13.50 per litre. the cost of olive oil is $18 per litre. work out the ratio cost of lemon juice in salad dressing : cost of olive oil in the salad dressing. give your ratio in the simplest form

$3 : $4 or 3 : 4

Step-by-step explanation: To find the ratio of the cost of lemon juice in salad dressing, you’ll have to replace $13.50 or 13.5 to (135/10), which doesn’t affect the solution. Next, simplify (135/10) to get 27/2. After, divide 27/2 by 18, which is the other part of the ratio. (27/2 ÷ 18) Your final answer or result should end up as 3/4 but since we’re dealing with fractions 3:4, which is the simplified form of $13.50 : $18.00.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
