Answer:
a. 6Pack of paint brushes for $12.99
b. 5 classes for $64.99
c. 12 pack of paper plates
Step-by-step explanation:
a.
I could buy a 6 pack of paint brushes for $ 12.99
or
buy 6 individual brushes for the price of $ 2.19 each.
6 x $2.19 = $13.14
first option is cheaper
b.
10 classes for s total of $150
$150 ÷ 10 = $15 (price per class)
5 classes for $64.99
$64.99 ÷ 5 = $12.998 (price per class)
c.
12 pack of paper plates for $2.29
25 pack for $4.99
$2.29 ÷ 12 = $0.1908 (price of one plate)
$4.99 ÷ 25 = $0.1996 (price for one plate)
Answer:
-9x + 10
Step-by-step explanation:
Y=x^2+2x
Btw the X^2 means x to the power of 2
Stacy's present age = x
Laura's present age = 8 + x
Laura's age next year = (8 + x) + 1
Also, Laura's age next year = 3x
Therefore,
3x = (8 + x) + 1
3x = 9 + x
3x - x = 9
2x = 9
x = 9/2
x = 4.5
Laura's present age = 8 + x = 8 + 4.5 = 12.5
