Simplify the following
7^1 =
4^0 =
6^-1 =

(I thought 7^1=7, 4^0=1, and 6^-1=0.16 but it is saying 0/1 points so???
Help!

try 6^(-1) = 0.17 or 1/6

Step-by-step explanation:

1/6 in decimal form is 1.66666... which technically should round to 1.7

if 1.7 isn't the right answer try righting it in exact form, 1/6 where there is no estimation

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
