Answer: 48) D. 4 49) C. N1.40
<u>Step-by-step explanation:</u>
A $2 postal money order actually costs $2.15
$10.00 ÷ $2.15 = 4.65
Since you can't purchase a fraction of a money order, the most you can buy is 4
4 money orders will cost $2.15 × 4 = $8.60
The change from $10.00 will be $10.00 - $8.60 = $1.40
Not equivalent expression is validated so I think it’s second one bye
4s + 3p = 85.50......multiply by 3
3s + 5p = 115.........multiply by -4
----------------
12s + 9p = 256.50 (result of multiplying by 3)
-12s - 20p = -460 (result of multiplying by -4)
---------------add
-11p = - 203.50
p = -203.50 / -11
p = 18.50 <=== the cost of a pair of pants
3s + 5p = 115
3s + 5(18.5) = 115
3s + 92.50 = 115
3s = 115 - 92.50
3s = 22.50
s = 22.50/3
s = 7.50 <=== the cost of each shirt
