Answer:
Where is the graph?
Step-by-step explanation:
To do it mentally means to do it in your head
first do 7 * 3 = 21 in your head
than do 7 * 0.8 = 5.6 ( this might be hard to do in your head but you know 7*8 = 56 so add a decimal since it is 0.8 not 8 )
Add : 21 + 5.6 = 26.6
Final Answer : 26.6
