Answer: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
U gotta add all the numbers then divide them by the amount of numbers there are. So divide them by 8 after u add
A in the payment or withdrawal amount because he is withdrawing money and paying someone else <span />
Answer:
13 quarters, 26 nickels.
Step-by-step explanation:
n will be number of nickels, q will be number of quarters, and we have 39 total coins
so n + q = 39 (number of nickels + number of quarters = 39 coins.
The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)
which means
n + q = 39
2q + q = 39
3q = 39
q = 13
and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels
LMK if you have questions.
If you want to double check the money,
n(0.05) + q(0.25) = 4.55 is the equation to use.
26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55
