Answer:
She bought
22 of the 52 cent stamps and
26 of the 23 cent stamps.
Step-by-step explanation:
Given :
Total stamp increase = 48
Let number of 52 cent stamp = x
Number of 23 cent stamp = 48 - x
The cost equation :
0.52*x + 0.23*(48-x) = 17.42
0.52x + 11.04 - 0.23x = 17.42
0.52x - 0.23x = 17.42 - 11.04
0.29x = 6.38
x = 6.38 / 0.29
x = 22
Hence,
She bought 22 ; 52-cent stamps
And (48 - 22) = 26, 23-cent stamps
Answer:
39 square feet
Step-by-step explanation:
P = 2( L + W)
actual length = 4 * 3 = 12
actual width = 2.5 * 3 = 7.5
P = 2 (12 + 7.5)
P = 2 ( 19.5)
P = 39 feet
