The answer is 40 you do 10 times 4 I hope it helped you you only need to multiply
Answer:
<em>30(30 - x) = 540 </em>
Step-by-step explanation:
A = l w
<u><em>30(30 - x) = 540</em></u>
59pounds * 5days = 295pounds
6.95pounds * 3breakfasts = 20.85pounds
12.50pounds * 1eveningmeal = 12.50pounds
295pounds + 20.85pounds + 12.50pounds = 328.35pounds
Wrote out the units just for clarity! Liz payed 328.25 pounds altogether.
The rate Ritz can eat apples is 8/15 apples per minute.
Set the rate (which is measured apples / minutes) equal to 16 apples / t minutes.
(8/15) = (16/t)
Cross multiply.
16*15 = 8t
t = 20
The answer is 30 minutes. You could solve the problem with basic reasoning as well. 16 is twice the number of apples as 8, so the time it takes to eat them will be double 15 minutes.
y=7x-1
-1 is the money she loses due to glores.
x = time
y = pay
