Answer:
E. 18 children are buying their lunches
F. Rock must pay $50 each month
Step-by-step explanation:
E.
To find a percentage you multiply the number by the percentage;
60 x 70%(0.70) = 42 children brought their lunches
But we need the amount <u>buying</u> their lunches so we would subtract 60 by 42;
60 - 42 = 18 buying their lunches
F.
Again, to find the percentage we multiply it by the original;
$800 x $25(0.25) = $200 Rock paid for the down payment on the sofa
Now we need to find how much Rock still needs to pay for the sofa;
$800 - $200 = $600 more needed to pay for the sofa
Lastly, we must find how much Rock will need to pay <u>each month</u> to pay the rest of the $600. There are 12 months in a year, so we divide that by the amount left;
$600 / 12 = $50 needs to be paid each month for a year
All you need to do is try the points and see which one makes the inequality TRUE.
(-1,-3) TRUE
-3 ≤ -|-1| -1
-3 ≤ -2
(0,0) FALSE
0 ≤ -|0| - 1
0 ≤ -1
(1,-1) FALSE
-1 ≤ -|1| - 1
-1 ≤ -2
Answer:
$15
Step-by-step explanation:
unit rate means how much he earns in 1 hour
so if he earns $60 in 4 hours
then you have to divide 60 by four
which gives you $15
that means he earn $15 in one hour
The correct answer is 18/30 which simplifies to 6/10. Hope this helps.
Hey there!
Finding our answer here will be very easy. We just multiply the sugar per batch by the number of patches.
2/3*6=4
Therefore Marcy will need 4 cups of sugar!
I hope this helps!
