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
25 % of 48 is 12
<em><u>Solution:</u></em>
Given that we have to find what percent of 48 is 12
Let "x" be the required percent
From given statement,
what percent of 48 is 12
Let us say,
x percent of 48 is 12
Writing it mathematically we get,
x % of 48 is 12
Evaluate the above expression to find "x"
Thus 25 % of 48 is 12
Zach is 14 bc...
