For 100 points each, write as many equations as you can to represent the story:
Rowan has read 18 fewer pages than Josh. If Josh read 31 pages, how many pages (x) has Rowan read?
(hint: a tape diagram will help you get them all)
31-18=x

For 200 points each, write as many equations as you can to represent the story:
McKenna ran 23 more miles last month than Mia ran. If McKenna ran 45 miles last month, how far (m) did Mia run?
(hint: a tape diagram will help you get them all)
200 points: m+23=45 (or 23+m=45)
200 points: 45-23=m
