Final answer:
To determine the cheaper plan, one typically looks at the cost per text for each plan and then multiplies this by the number of texts (up to 150 in this scenario). The plan that results in the lowest total cost is the cheaper plan.
Step-by-step explanation:
Without knowing the exact costs of Plan A and Plan B for under 150 texts, it's impossible to definitively say which plan is cheaper. However, the way to determine this would typically be to look at the cost per text under each plan, then multiply that by the number of texts (in this case, up to 150). For example, if Plan A charges $0.05 per text and Plan B charges $0.04 per text, it's clear that Plan B would be cheaper for 150 texts or less. You would simply multiply 150 by $0.04 (which equals $6.00) and compare that to 150 multiplied by $0.05 (which equals $7.50). In this hypothetical scenario, Plan B is cheaper.
