the price of a sweatshirt at a local shop is twice the price of a pair of shorts. the price of a t-shirt at the shop is $4 less than the price of a pair of shorts. brad purchased 3 sweatshirts, 2 pairs of shorts, and 5 t-shirts for a total cost of $136.
-let w represent the price of one sweatshirt, t represent the price of one t- shirt, and h represent the price of one pair of shorts. write a system of three equations that represents the prices of the clothing.

Here's what I get  

Step-by-step explanation:

w = 2h means the price of a sweatshirt is twice that of a pair of shorts.

t = h - 4 means the price of a T-shirt is $4 less than that of a pair of shorts.

3w + 2h + 5t = 136  means 3 sweatshirts, 2 pr of shorts, and 5 T-shirts have a total cost of $136.

Your system of three equations is

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!

is there any other information given for this problem? this is not enough information.
