The expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?
he spent 6p dollars on gasoline.
he spent n + p dollars in all.
he bought 15 gallons of gasoline.
he bought 6 dollars worth of snacks.

c) He bought 15 gallons of gasoline.

Step-by-step explanation:

First, let’s analyze the equation 15n + 2(3p) and its meaning:

As n represents the price of each gallon of gasoline he bought and is multiplied by 15, we can deduct that he spent 15 times the price of one gallon (that's means he bought 15 gallons of gasoline and paid 15n dollars for that).

On the other hand, we have 2(3p), that's 2*3*p=6p.

p is the cost of each snack, as before we can deduct he bought 6 snacks and he paid 6p dollars.

Now let’s analyze the options :

a) Wrong. He spent 6p dollars on snacks.

b) Wrong. He spent 15n dollars on gasoline and 6p dollars on snacks, so he spent 15n + 6p in all.

c) Correct.  

d) Wrong. He bought 6p dollars worth on snacks.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

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!
