Teachers were asked what their favorite ice cream was. The ratio of teachers that prefer rocky road to mint is 5 to 2. If there

DerKrebs [107]

28 teachers prefer mint.

Step-by-step explanation:

Given,

Total number of teachers = 98

Ratio of teacher that prefer rocky road to mint = 5:2

Let,

x be the original number.

Teachers who like rocky road = 5x

Teachers who like mint = 2x

$5x+2x=98\\7x=98$

Dividing both sides by 7

$\frac{7x}{7}=\frac{98}{7}\\x=14$

Teachers who prefer mint = 2x = 2(14) = 28

28 teachers prefer mint.
