Maria has $2.43 in quarters and pennies in her wallet. she has twice as many pennies as quarters. how many coins of each type does she have?

Given maria has in the pennies & quarters.

she has twice as many pennies  as quarters.

find out the coins

let us assume the  quarters are x

than the pennies are 2x.

Formula

 value of the pennies +  value of the quarters = total value of coins

1 quarters =$ 0.25

1 pennies = $0.01

Thus

0.25x + 0.01 (2x) = 2.43

0.27 x = 2.43

x = 9

2x = 18

i.e the number of quarters are 9 and the number of pennies are 18.
