Number of nickels plus number of dimes equals total number of coins
so
n + d = 40
then they tell us that "there are seven times as many dimes as there are nickels"
this translates to
d = 7n
we then plug that into our first equation
and get
n + 7n = 40
then we solve for n
add like terms
8n = 40
then divide both sides by 8
n = 40/8 = 5
therefore Jimmy has 5 nickels

Answer: approximately 5.5814 calories
==================================
We start off with this ratio
4.3 ounces : 24 calories
Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side
4.3 ounces : 24 calories
4.3/4.3 ounces : 24/4.3 calories
1 ounce : 5.5814 calories
This value is approximate to four decimal places.
