Answer:
The inequality is 15<=2t+8
Solution is 3.5<=t
Line graph 1 is correct
Step-by-step explanation:
For the first page, t is the number of pounds of white flour Mateo can buy and he has $15 in total (note that he can't spend more than $15) and has already paid $8 on whole wheat, so:
15<=2t+8
Solve with PEMDAS and the answer is
3.5<=t
Taking 3.5<=t, we see that the number of pounds is less than 3.5, so line graphs 2 and 4 are cancelled out. We would assume that he would only be allowed to pay for a whole pound (a whole number) so line graph 1 is the correct solution since line graph 4 includes non-whole numbers (fractions and decimals).
