At a supermarket, John spent 1/5 of his money on fresh fruits and vegetables, 1/3 on meat products, and 1/10 on bakery products. If he spent the remaining $11 on candy, how much did John spend at the supermarket?
Choose the correct option.
A) $20 B) $30 C) $50 D) $90 E) $110
Let's let T = total number of dollars spent at the supermarket. With this variable we can set up an equation and determine T.   We are given that John spent 1/5 of his money on fresh fruits and vegetables, or (1/5)T, 1/3 on meat products, or (1/3)T, and 1/10 on bakery products, or (1/10)T. We are also given that he spent the remaining $11 on candy. Since we know where all his money was allocated, we can sum these values together and set the sum to T. So we have:   (1/5)T + (1/3)T + (1/10)T + 11 = T   To get rid of the fractions we can multiply the entire equation by 30, and we obtain:   6T + 10T + 3T + 330= 30T   19T + 330 = 30T   330 = 11T   T = 30   John spent $90 at the supermarket.   Answer: $30
