Answer:
$7.14
Step-by-step explanation:
Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.
p + d + q = 45 . . . . . . . . there are 45 coins in the collection
2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies
p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies
Substituting the last two equations into the first gives ...
p +(p +4) +(2p +5) = 45
4p = 36 . . . . . . . . . . . . . subtract 9
p = 9 . . . . . . . . . . . divide by 4
d = 9 +4 = 13
q = 2(9) +5 = 23
The value of the collection is ...
23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14
The coin collection is worth $7.14.
Answer:
6.75 grams
Step-by-step explanation:
Total amount of lemonade with Samantha = 4 1/2 gallons
= (4*2 + 1)/2 gallons = 9/2 gallons = 4.5 gallons
Amount of fat in 1 gallon of lemonade = 1.5 grams
To find amount of fat in 4.5 gallons lemonade
we multiply both side of equation with 4.5
Amount of fat in 1*4.5 gallon of lemonade = 1.5*4.5 grams = 6.75 grams
Thus,
there is 6.75 grams of fat in all the lemonade Samantha has for the party
