If there are 15 work days until the day she begin tio sell the basket how many basket will she have to sell

So she has 13 baskets over from last year

then y - intercept would be 13

and make 12 more each day

so the slope would be 12

and there is 15 work days

y = 12x + 13

y = 12 (15) + 13

y=180+13

y=193

just remember the linear equation then you will get to understand the problem
