Question

Tatum plans to buy some personalized sticky notes for her home office. The graph shows a proportional relationship between the number of packs of sticky notes she can buy and the total price. If Tatum has $30.50 to spend on sticky notes, how many packs can she buy?

Answer 1

From the graph, it appears that a pack of sticky notes costs $11. 3 packs of sticky notes cost $33, which exceeds her budget. Therefore, she can only buy 2 packs of sticky notes.

3/33=?/30.50
3 × 30.50/33
91.5/33= 2.77

Answer 2

this graph shows y=11x
so sub 30.5into y,
you'll get 2.77
so she can buy 2packs at most
