b) 221 texts
Explanation:
If we plug in 1 for the month variable we get
92.30=26+0.3t
subtract 26 from both sides and we get 66.3=0.3t
Divide by 0.3 and we get t=221
Answer:
Here u go lil bro,
550w>4500+200w
Explanation:
Since she earns $550 per week, Josephine's earnings can be represented as 550w, where w is the number of weeks.
Her costs are $200 per week, or 200w, plus the 4500 start up costs; this gives us 200w+4500.
We want a profit; this means the amount she earns, 550w, must be greater than the costs, 200w+4500:
550w > 200w + 4500, or
550w > 4500 + 200w
