Answer:
17, 18, 19, 20
Explanation:
Let the numbers be x, x + 1, x + 2, x + 3
Their sum is equals to 74
x + x + 1 + x + 2 + x + 3 = 74 (group the variables)
x + x + x + x + 1 + 2 + 3 = 74 (simplify)
4(x) + 6 = 74 (subtract both sides by 6)
4x = 68 (divide both sides by 4)
x = 17
Other numbers:
x + 1 = 17 + 1 = 18
x + 2 = 17 + 2 = 19
x + 3 = 17 + 3 = 20
Let x be the number of quarts of water it sells at lunch
Dinner = 2x - 36
Lunch = 2x
2x + 2x - 36 = 4x - 36
4x - 36 = 144
144 - 36 = 4x
4x = 108
x = 108 divided by 4 = 27
2x = 27 x 2 = 54
The restaurant sells 54 quarts of water at lunch.
