Answer:
4.513451241 sq feet wide x 12.41255213 sq feet
Step-by-step explanation:
(820*7)-(480*7)=? This is how to solve the equation
A + b = 13
22 a + 18 b = 258
------------------------
a = 13 - b
22 * ( 13 - b ) + 18 b = 258
286 - 22 b + 18 b = 258
- 4 b = 258 - 286
- 4 b = - 28
b = ( - 28 ) : ( - 8 ) = 7
a = 13 - 7 = 6
Answer:
6 tour packages a and 7 tour packages b were sold.
