Answer 1

Bob's gift shop sold a record number of cards for Mother's Day. One salesman sold 22 cards, which was 20% of the cards sold for Mother's Day. How many cards were sold for Mother's Day?

Answer:

110 cards were sold on Mother's Day?

Answer 2

Answer:

110 cards were sold on Mother's Day

Step-by-step explanation:

Bob's gift shop sold 20% of all the cards sold on Mother's Day.

Let the number of cards sold on Mother's day be m

Bob sold 20% of m or 0.2m

We know that 0.2m is 22, so now we can solve for m

• 22 = 0.2m
• 22 ÷ 0.2 = m
• 110 = m

110 cards were sold on mothers day

Note

We know that 0.2 is 1/5, so instead of dividing each side by 0.2, we could have multiplied both sides by 5

• 22 = 0.2m
• 22 * 5 = 1/5m * 5
• 110 = 1m
• 110 = m
