Answer:

[tex]1.50R = 18.0[/tex]

Step-by-step explanation:

Given

Represent Mugs with M and Refills with R

[tex]M = \$8.95[/tex]

[tex]R = \$1.50[/tex] per refill

[tex]Total = \$26.95[/tex]

Required

Determine the equation

If 1 refill costs $1.50, then

R refills will cost 1.50 * R

The relationship between the given parameters is:

[tex]Total = M + Refills[/tex]

Substitute values for Total, M and Refills

[tex]26.95 = 8.95 + 1.50*R[/tex]

[tex]26.95 = 8.95 + 1.50R[/tex]

Solve for 1.50R

[tex]1.50R = 26.95 - 8.95[/tex]

[tex]1.50R = 18.0[/tex]

Hence, the equation to solve the value of R is [tex]1.50R = 18.0[/tex]
