Answer:
p * 90 = 36
p = 40%
Step-by-step explanation:
To find the percentage of sandwiches that are pastrami, multiply the percentage(p) by the total amount of sandwiches(90) and set it equal to the amount of pastrami sandwiches(36):
p * 90 = 36
To find the value of p, divide both sides of the equation by 90 to isolate p:
90p/90 = 36/90
p = 0.4
0.4 is the decimal form of 40%.
Hope this helps :)
