including shipping and tax. he uses
rounding to estimate the total cost:
(5 x $1) + $15 = $20. neil says his gift
certificate is worth more than the total
cost. is neil correct? explain.

Neil is not correct

Step-by-step explanation:

Let us calculate the total cost of the of the apps and headphone without estimation.

He wants to buy 5 apps priced at $0.99 each

Total cost of the 5 apps will be

5 × 0.99 = $4.95

He also wants to buy headphones priced at $15.49.

Since this includes shipping and tax. The total cost the 5 apps and headphone is 4.95 + 15.49 = $20.44

Neil only has a $20 gift certificate for an online store. This is actually lesser than the total cost of the items.

So Neil is wrong

Even if he estimated by rounding up, the most reasonable estimate would be

$1 per app and the 5 apps will cost $5

The headphone will be $15.5

The total would be 5+ 15.5 = $20.5.

This is still more than his gift certificate
