At an amusement park, you pay a $15 entrance fee and then $4 for each ride you go on.
how much will it cost if you go on seven rides?

is this proportional

43

Step-by-step explanation:

4(cost) x 7(amount of rides)=28(total)

43(total) + 15(fee)= 28(answer)

51-50

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
