Question

Felicia, Ingrid, Meiko and Tatiana spent a total of $31.50 at the baseball game. Felicia spent $4.25. Ingrid spent twice as much as Felicia. Meiko spent $1.90 more than Ingrid. How much did Tatiana spend?

Answer 1

`Tatiana = \$8.35`

Explanation:

Given

`Total = \$31.50`

`Felicia = \$4.25`

`Ingrid = 2 * Felicia`

`Meiko = \$1.90 + Ingrid`

Required

Determine amount spent by Ingrid

We have that:

`Ingrid = 2 * Felicia`

Substitute $4.25 for Felicia

`Ingrid = 2 * \$4.25`

`Ingrid = \$8.5`

We also have that:

`Meiko = \$1.90 + Ingrid`

Substitute $8.5 for Ingrid

`Meiko = \$1.90 + \$8.50`

`Meiko = \$10.40`

The total can be represented as thus:

`Felicia + Ingrid + Meiko + Tatiana = Total`

`\$4.25 + \$8.50 + \$10.40 + Tatiana = \$31.50`

`\$23.15+ Tatiana = \$31.50`

`Tatiana = \$31.50 - \$23.15`

`Tatiana = \$8.35`
