The required equation is 10x + 7 > 85.
What is an equation?
An equation is a relation between two expressions formed by the composition of terms separated by mathematical operators.
Terms are combinations of variables and constants.
How to solve the question?
In the question, we are informed that Mr. Han is buying shirts for his team. He already has 7 in his office and needs a total of 85 shirts. They are sold in packs of 10.
We are asked to write an equation to show how many more packs of shirts he needs.
We assume the number of packets needed to be x.
A pack consists of 10 shirts.
Therefore, the number of shirts in x packets is represented by the term 10x.
The number of shirts he already has is represented by the term 7.
Therefore, the total number of shirts he will have after purchasing x packets of shirts is represented by the algebraic expression 10x + 7.
As Mr. Han needs 85 shirts in total, the total number of shirts Mr. Han will have must be greater than 85. This can be represented by the equation:
10x + 7 > 85.
Therefore, the required equation is 10x + 7 > 85.
