How many pennies will Grace have from her dimes? ** Grace will have 10 x 10 = <<10*10=100>>100 pennies from her dimes.
How many pennies will Grace have from her nickels? ** She will have 10 x 5 = <<10*5=50>>50 pennies from her nickels.
How many pennies will Grace have by exchanging her 10 dimes and 10 nickels? ** Therefore, she will have a total of 100 + 50 = <<100+50=150>>150 pennies.
