Box со 1. A man had three GH¢50,00, seven GH¢20.00 and five GH¢10.00 notes in his
pocket, if he bought a bicycle for GH¢80.00 each, how many GH¢20.00 and
GH¢10.00 notes did he have left?

The man has 6 GHc20.00 notes and 4 GHc10.00 left

Step-by-step explanation:

Given

Amount = 3 GH¢50.00, 7  GH¢20.00 and 5 GH¢10.00

Spendings = GH¢80,00

Required

Determine how many GH¢20.00 and  GH¢10.00 notes left

The amount he has can be represented as:

This can be represented as:

Represent:

GHc50.00 with x, GHc20.00 with y and GHc10.00 with z

So, we have:

Subtract the spendings from the total to get amount left

Collect Like Terms

Recall that, we have represented:

GHc50.00 with x, GHc20.00 with y and GHc10.00 with z

This means that, the man has 6 GHc20.00 notes and 4 GHc10.00 left
