Jack purchases 12 gallons of gas on monday. he uses 2/3 of the amount purchased commuting to and from work during the week and an additional 2 gallons running errands. how many gallons of gas does john use from work and errands?

Using operations with fractions, John uses 10 gallons from work and errands.

Solution:

Jack purchases 12 gallons of gas on Monday.

He uses 2/3 of the amount purchased commuting to and from work during the week:

(2/3)(12)=(2/3)(12/1)=(2*12)/(3*1)=24/3=8

Then John uses 8 gallons commuting to and from work during the week.

And an additional 2 gallons running errands.

John uses in total from work and errands= 8 gallons+2 gallons

John uses in total from work and errands= 10 gallons

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
