Brandon and Rey are both hired to work at the school fun fair. The school pays

Brandon $6.80 per hour to work outside

and Rey $8.30 per hour to work inside.

To calculate how much the school owed

them, they used the formula 6.8h 1 8.3h,

where h is the number of hours they

worked.

If they both worked 6 hours, how much

did they earn together?
