Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month. Write and solve an equation that can be used to determine gg, the number of gigabytes of data Sofia can use while staying within her budget.

To stay within budget, she must use 4.5 gigabytes.

Step-by-step explanation:

Giving the following information:

Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.

First, we need to establish the total cost formula:

Total cost= 58.5 + 4*x

x= number of gigabytes

Now, we isolate x:

76.5= 58.5 + 4x

18/4= x

4.5= x

To stay within budget, she must use 4.5 gigabytes.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
