Betty saves $161 a month. She saves $141 less each month than Jack. How much will jack save in 2 years?
tresset_1 [31]

Given that Betty saves $161 per month which is $141 less than Jack per month. find the amount that Jack will save in 2 years.

First, find how much Jack saves. We can do this buy adding 141 to 161 since Betty saves 141 less meaning we can reverse it by adding it.

141 + 161 = 302

Now, that we know how much Jack saves per month.

Then, we have to find out how many months are in 2 years.

We already know that there is 12 months in a year, so for 2 years, we can simply multiply by 2.

12 x 2 = 24

Therefore, there are 24 months in two years.

Lastly, multiply 24 months by the amount that Jack saves to get the amount in total.

24 x 302 = 7,248

Thus, Jack will save approximately $7,248 in 2 years.

Nataliya [291]
2/3 of a page in 5/12 of a minute

Multiply both fractions by 3/2

\frac{2}{3} \times \frac{3}{2} = 1

\frac{5}{12} \times \frac{3}{2} = \frac{5}{4} \times \frac{1}{2}=\frac{5}{8}

So, Ethan can read 1 page in 5/8 of a minute.
