Question

Translate to an equation:

b $3 bows and r $5 rolls of wrapping paper total $45

Graph the equation and use the graph to determine three different combinations of bows and rolls of wrapping paper that total $45

Answer 1

It's written out for you, just change it to algebra.\[3b+5r=45\]After you graph it, look for places it crosses the intersection of whole numbers (i.e., you don't buy half an item).

Answer 2

As a hint, look at values of b that are multiples of five.

Answer 3

so would r be 9 and b would be 15?

Answer 4

Actually, the question wants you to find combinations of b and r. So, if you have no bows, you get nine rolls of paper (0,9). If you have five bows, (5,6); ten,(10,3). If you have fifteen bows, you don't get any paper (15,0).

Answer 5

okay so i would plot these on the graph

Answer 6

That's what the instruction says.

Answer 7

okay thanks
