Aknife is twice the cost of a spoon. 8 spoons and 12 knives cost £46.08. work out the cost of 1 knife.

A knife costs £2.88.

Step-by-step explanation:

Create two equations using what you know to show the problem.

k = 2s

12k + 8s = 46.08

Substitute the first equation in for k, then isolate s to find how much spoons cost.

12(2s) + 8s = 46.08

24s + 8s = 46.08

32s = 46.08

s = 1.44

A spoon costs £1.44. To find the price of a knife, double the cost of a spoon:

1.44 * 2 = 2.88

A knife costs £2.88.

b. x- 48 =120

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
