Answer: a total of 148 cards were sold for Mother’s Day at Bob’s gift shop.
Step-by-step explanation: Let’s solve this problem by scaling up. If one salesman sold 37 cards, which was 25% of the total cards sold for Mother’s Day, then we can find the total number of cards sold by dividing 37 by 0.25: 37 ÷ 0.25 = 148.
So, a total of 148 cards were sold for Mother’s Day at Bob’s gift shop.
