Angelina buys a pair of earrings for 12.50 plus 5% tax. Elizabeth buys a rig for 8 dollars plus 5% tax. What is the sum, in dollars, that Angelina and Elizabeth payed, including tax.

$21.53

Step-by-step explanation:

Take 12.50 and multiply it by 5%, it equals 0.625. That number represents how much the tax costs, so add it to 12.50, it equals 13.125.

You then have to add the ring.

Take 8 and multiply it by 5%, it equals 0.4. That is the tax, so add it to 8, it equals 8.4.

Add them together, 21.525

Then round to the nearest hundredth.

$21.53 is the final answer.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
