Hi. pls, help me with these questions.

A pencil cost $1.20 and a pen cost $2.90. Jasimah bought an equal number of such pencils and pens. She spent $32.30 more on the pens than on the pencils. How many pencils and pens did she buy altogether?

Muthu spent $121 on a pair of shoes and 4/7 of the remaining money on a number of shirts. He had 1/6 of the original sum of money left. How much money did he have at first?
