Answer:
5(P - 1.00) + 3(P - 0.75)
Step-by-step explanation:
Cost of a package in store A = $P
Discount offered at store A = $1.00
Price paid per package at store A = Cost of a package in store A - Discount offered at store A
= P - 1.00
Cost of a package in store B = $P
Discount offered at store B = $0.75
Price paid per package at store B = Cost of a package in store B - Discount offered at store B
= P - 0.75
Total cost of 5 packages at store A and 3 packages at store B = 5(P - 1.00) + 3(P - 0.75)
first, spread the parenthesis. y+2=1/2x-1.5
second, add 1.5 to both sides. y+3.5=1/2x
third, multiply by 2. 2y+7=x
if you are solving for y, do not do the third step, instead, subtract by 3.5. y=x-3.5
hope this helps!
ANSWER: x=2y+7 or y=x-3.5
Answer:
Size of N(S) = 90, or S=90
Step-by-step explanation:
So since there are 10 items:
Each single item has 9 possibilities to be paired with, since it is drawn without replacement, and 1 item can't be drawn again.
So : 10 items x 9 possibilites = array of 90
SO ANSWER : 90
Hope I helped :)
