Ответ:
Number of small boxes shipped = 10
Number of large boxes shipped = 12
Step-by-step explanation:
Let x be the number of small boxes
and
y be the number of large boxes
According to the first statement, a total of 22 boxes were shipped
Equation 1 will be:
x+y=22
And
According to 2nd statement, Total weight was 1350 and we know the weight of one small box is 45 and large box is 75
So equation 2 will be:
45x+75y=1350
We will use the substitution method for solving the equation
So from equation 1
Putting the value of x in eqn 2
Putting the value of y in eqn 1
So,
Number of small boxes shipped = 10
Number of large boxes shipped = 12 ..
