Answer: $10
Step-by-step explanation:
Assume the price of the phone case is x.
Assume the price of the charging cord is y.
Discounted price for phone case : 15% * x
= 0.15x
Discounted price for charging cord = 0.15y
Expression is therefore:
0.15x + 0.15y = 4.20
0.15 * 18 + 0.15y = 4.20
2.7 + 0.15y = 4.20
0.15y = 4.2 - 2.7
y = 1.5/0.15
y = $10

A sequence is defined as an arrangement of numbers in a particular order. On the other hand a series is defiend as the sum of the elements of a sequence!
Answer:
One person ordered chicken, and five people ordered steak.
X=Chicken
Y=Steak
Step-by-step explanation:
X+Y=6
14x + 17y= 99
5.5 • 5= 27.5+27.5+65+65+71.5+71.5=328
13•5=65
13•5.5=71.5
THE ANSWER IS 328
