Question

Maria and Farida has 250 beads altogether. After Maria used 18 beads to make a bracelet and Farida gave away 2/5 of her beads, they have the same number of beads left. How many beads did Maria have at first?

Answer 1

Maria had 105 beads

Explanation:

Let x the number of beads Maria had

Let y the number of beads Farida had

We know because of the problem that

x + y = 250

x -18 = 3/5* y

x -3/5*y = 18

We solve this system of equation with a graphing tool

(intersection of both lines)

Answer

x = 105

y = 145
