Well we first need to add up all the purchases, 2 sandwiches are 6.86 each so by multiplying that we get 13.72. Next are the burgers, 3.44 x 4 is 13.76. We don’t need to multiply fries since there’s only one, so that’s just 3.19. Finally there are 4 drinks for 1.52 which gives us 6.08. We need to add these prices all together to get the total. 13.72 + 13.76 + 3.19 + 6.08 = 36.75. In order to find ten percent we multiply 36.75 by .10 which gives us 3.675. Double of 3.675 is 7.35. The price 13.72 (14 rounded) needs to be added with the tax 3.675 (4 rounded) and once again add 7.35. All together we get 25. Are there no other answer choices? Unless I did something wrong I’m sure this is right
Answer:
minutes
Step-by-step explanation:
Let's find unit rate of each.
<u>Jada</u>
2 scoop in 5 minutes
So,
1 scoop in 5/2 = 2.5 minutes
<u>Noah</u>
3 scoop in 5 minutes
So,
1 scoop in 5/3 = 1.25 minutes
These are the times. Time and rate are inverses of each other. So the rates of each is:
Jada = 1/2.5 = 0.4
Noah = 1/1.25 = 0.8
Working together, we add the rates and find the time:
(0.4+0.8)*t = 1
1.2t = 1
t = 1/1.2 = minutes
So, they take minutes to eat one scoop, working together
Answer:
part 1: a-50=5. a=55
Step-by-step explanation:
because fifty five minus 50 is equal to 5
Answer is Correct. She could have also subtracted 100 from both sides, then divided by .
6a-2 (a-1) in simplest form is 4a+2.
