6 gina has some flowers. she gives 7 flowers to friends. now she has 6 flowers. how many flowers does gina have to start?
____ flowers

Explanation:

Step1: Analyze 40 + 30 place values

40 = 4 tens, 30 = 3 tens

Step2: Sum the tens place values

$4 \text{ tens} + 3 \text{ tens} = 7 \text{ tens}$

Step3: Calculate total eggs sold

$50 + 20 = 70$
