Help me if u can I’ll really appreciate it !<3

Step-by-step explanation:

slope intercept form is y = mx + b

where m = slope

and b = y intercept

in this context the y intercept is 2

and the slope is 0.15

the equation we have is

y = 0.15x + 2

to find the cost after 31 days, we’ll plug in 31 for x

y = 0.15(31) + 2

y = 4.65 + 2

y = 6.65

so the cost after 31 days is $6.65

you already gave the answer
