Write and equation that represents how much money she will need to save each week to reach her
goal.

Katelynn has $285 already saved. The bike she likes starts at 475. It starts at, it's not exactly. However, we are looking for the least amount she needs to save. Therefore, we need to subtract what she has saved from the least amount she is trying to save or reach. least amount needed $475 minus-saved $285 this equals $190.

Step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or
