5. Lauren has $50 to spend at the Strawberry Festival. She spends $ 10 on admission and $12 on strawberry shortcake. She wants t
olga55 [171]

For this case we have that Lauren's initial amount of money was $ 50, if he spends $10 and $12 on admission and strawberry pie respectively we have:

$50 - ($10 + $12) = $50- $22 = $28

That is, she has $ 28 left

n: Let the variable that represents the amount of games Lauren can play.

Then, it must be fulfilled that:

0.75n \leq28\\n \leq \frac {28} {0.75}\\n \leq37.33

Thus, Lauren can play 37 times the game (at most)

The frist brand is 30% and the second on is 55% in order to obtain 30 gallons of mixture that contains 35% how many gallons of e
snow_tiger [21]

yeet


first brand quantity is x

2nd brand quantity is y


x+y=30

0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5

solve for x and y

multiply first equation  by -0.3

-0.3x-0.3y=-9

add to 2nd equation


0.3x-0.3y=-9

<u>0.3x+0.55y=10.5 +</u>

0x+0.25y=1.5


0.25y=1.5

divide both sides by 0.25

y=6

sub back

x+y=30

x+6=30

x=24


you need 24 gallons of the first brand and 6 gallons of the 2nd brand
