Question

pls help me ;.;

Answer 1

x is # of nickels, y is # of pennies as stated in the problem

he has "no less than 20 coins" so x + y must be greater than/equal to 20

their value is no more than $0.40 combined. the value of x nickels is 0.05x, same logic with pennies being 0.01y. so 0.05x + 0.01y is less than/equal to 0.40

write and graph both inequalities. then look for a point within both regions. since x and y represent coins, you can only look for positive integer values of x and y.
