astraxan [27]
There are 20 nickels and 10 pennies.

20 cents x 5 is $1.00 and 10 cents x 1 is 10 cents so it is $1.10 because a nickel is 5 cents so 20x5 is a dollar and a penny is worth 1 cent and 10 pennies is 10 cents so $1.00+$0.10=$1.10 brainliest is appreciated! :)

Jane is saving to buy a cell phone. She is given a $100 gift to start and saves me
Dmitriy789 [7]

Answer:

See explanation

Step-by-step explanation:

Jane is given a $100 gift to start and saves $35 a month from her allowance.

  • After 1 month, Jane has saved \$100+\$35=\$135;
  • After 2 months, Jane has saved \$100+2\cdot \$35=\$170;
  • After three months, Jane has saved \$100+3\cdot \$35=\$205;
  • and so on

In general, after x months Jane has saved

\$100+x\cdot \$35=\$(100+35x).

This means that it makes sense to represent the relationship between the amount saved and the number of months with one constant rate (in this case the constant rate is 35). It makes sense because the amount of money increases by $35 each month. Since the amount of increase is constant, we get constant rate. Also the initial amount is known ($100), so there is a possibility to write the equation of linear function representing this situation.
