35X+5Y

## Ans 2:

Class : Class 6
yeah the answer is 35x+5y. because see prachi spends x rupees daily and saves rupees y per week and so find her income after 5 weeks. so here we will convert the 5 weeks to days and so 7*5=35 then 35 multiply by x rupees so we will get that how much she spends daily. then we multiply 5 and y so 5y and then after wards we will get the answer. 35x + 5y. we had done this to find the spend money and to find the save money and then after wards we will add them both.
