Answer 1

A strategy you could use to find the cost of 1 package of glass beads is to first calculate the cost of the vases and the sales tax. To do this, multiply the cost of each vase ($3.59) by the number of vases (2) to get the cost of the vases ($7.18). Then, multiply the sales tax rate (7%) by the cost of the vases ($7.18) to get the total sales tax ($0.50).

Next, subtract the cost of the vases ($7.18) and the total sales tax ($0.50) from the total amount she paid ($28.50) to get the cost of the glass beads ($20.82). Finally, divide the cost of the glass beads ($20.82) by the number of packages of glass beads (4) to get the cost of 1 package of glass beads ($5.20).
