Answer:
20n
Step-by-step explanation:
One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.
1 pretzel = 20 calories
n pretzel = x
Cross Multiply
x × 1 pretzel = n pretzel × 20 calories
x = n pretzel × 20 calories/1 pretzel
x = 20 n
Therefore, an algebraic expression for the total number of calories in n pretzels = 20n
Step-by-step explanation:
Since there is 2 unknown variable ,
so we need 2 equation to find their values.
=3*100 + 17*10 + 13*1 + 1*0.1 + 2*0.01
=300 + 170 + 13 + 0.1 + 0.02
= 483.12
