An electrician changes a flat fee plus an hourly rate for a service call. she changes a total of $94 for a 3-hour service call on monday and $130 for a 5-your service call on tuesday. how much should she change for 2-hour service call?

$56 (might be wrong but thatś what I got)

flat rate is $40  + $ 18 per hour

3 hour = $18 x 3 = $54  + flat rate $ 40 = $ 94

5 hour = $ 18 x 5  = $90  + flat rate $ 40 = $130

2 hour = $ 18 x 2 = $ 36 + flat rate $ 40 = $ 76

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
