Answer:
The amount of change he should received is
$100 - $56.875
= $43.125
= $43.13
Step-by-step explanation:
Length of window trim = 32 and 1/2 ft
Cost per foot = $1.75
Amount paid = $100
Total cost of window trim = 32.5×1.75 = $56.875
The amount of change he should received is
$100 - $56.875
= $43.125
= $43.13
Answer:
79°
Step-by-step explanation:
since this figure goes around completely, the sum would be 360°
1 and 3 are equal, so you would multiply 101 by 2
101 × 2 = 202
subtract 202 from 360
360 - 202 = 158
4 and 2 are equal, so divide 158 by 2
158 ÷ 2 = 79
so angle 4 = 79°
