Answer: The cost of shipping 6 pounds is $ 9.00
The maximum number of pounds he can ship is 74 pounds.
Explanation:
To find the cost for the first 6 pounds, multiply $1.50 × 6 = $9.00
To find out how much more he can ship, subtract: $26 - $9 = $17
The number of pounds that can be shipped for $0.25 is 17 divided by .25
17/.25 = 68
The total maximum weight is 6 + 68 = 74 pounds.
Check: 6 pounds for $ 9.00 plus 68 pounds for $17.00
The money adds up to $26 and the weight adds up to 74 pounds.
