What is the surface area of this design? help fast please!!

answer:

490 in

Step-by-step explanation:

1st prism:

1st face: 5 times 5= 25 and there are 2 of them so it is 50 in

2nd face: 5 times 8 = 40 and there are 4 of them so it is 160 in

2nd prism:

1st face:  10 times 2= 20 and there are 4 of them so it is 80 in

2nd face: 10 times 10=100 and there are 2 of them so it is 200 in

now you add them all 50+160+80+200= 490 in

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
