Belen has two kinds of pennies, a 2010 penny and a 1959 penny. The 2010 penny is three-quarters of the weight of the 1959 penny. If the 1959 penny weighs 48 grains, what is the combined weight of the two pennies?
If the 1959 penny weighs 48 grains, the 2010 penny weighs 3/4 * 48 grains = <<48*3/4=36>>36 grains
The combined weight for the two is 36 grains + 48 grains = <<36+48=84>>84 grains
