Answer:
Discount of $12.50.
Sale price is $37.50.
Step-by-step explanation:
Since the dress is "Marked save 25%" this means yuo pay 75% of the $50 price. Remember, 100-25 = 75. This means you pay 0.75*50 = $37.50 and yuo got a discount of $12.50.
$50 - 37.50 = 12.50
Answer:
252 children and 395 adults
Step-by-step explanation:
Make a linear system of equations, where x represents the number of children and y represents the number of adults
x+y=648
1.50x+2.25y=1269
solve using substitution, so y=648-x,
then substitute this into the second equation, so you get 1.50x+2.25(648-x)=1269,
solve for x and you will get x equals the 252
then substitute this into the first equation, so you get 252+y=648
solve and you will get y=395
4x² + 43 = 120
4x² = 120 - 43
4x² = 77
x² = 77/4
x² = 19.25
x = ±√19.25
x = ±4.39
