Answer: 2.60+ 2.50 m
Explanation:
Hi, the cost of Casey's family is equal to the price of 1 small drink (1.10) plus the price of a medium drink (1.25) multiplied by the number of medium drinks bought (m).
Same process for Anika's Family.
Casey's family cost: 1.10+ m 1.25
Anika's family cost :m1.25+ 1.50
Combining the expressions:
1.10+ m 1.25+m1.25+ 1.50
1.10+1.50+1.25m+1.25m
2.60+ 2.5 m
Total cost of both orders = 2.60+ 2.50 m
