Answer: she invested $2500 at the rate of 10%.

she invested $1500 at the rate of 6%.

Step-by-step explanation:

Lisa invests $x in bond A and $y in bond B.

Lisa invests $4,000 in two types of bonds, bond A and bond B. This means that

x + y = 4000

Bond A offers a 10% return, and bond B offers a 6% return. Therefore,

Interest on bond A is 0.1x

Interest on bond B is 0.06y

Her total return on the investment is $340. It means that

0.1x + 0.06y = 340

Therefore, The system of linear equations defining the situation is

x + y = 4000

0.1x + 0.06y = 340 - - - - - - - - - - -1

Substituting x = 4000 - y into equation 1, it becomes

0.1(4000 - y) + 0.06y = 340

400 - 0.1y + 0.06y = 340

- 0.1y + 0.06y = 340 - 400

- 0.04y = - 60

y = - 60/ - 0.04

y = 1500

x = 4000 - 1500

x = 2500

Katie wants to buy some popcorn for her family at the theater. Each small tub of popcorn costs $3 and each large tub of popcorn
Molodets [167]

For this case we propose a system of equations:

x: Represents the amount of small popcorn tubs

y: Represents the amount of large popcorn tubs

According to the data we have to:

3x + 4y = 24 (Spending all the money in your wallet)

x + y = 7 (Buying 7 popcorn tubs)

From the second equation we have:

x = 7-y

Substituting in the first equation:

3 (7-y) + 4y = 24\\21-3y + 4y = 24\\21 + y = 24\\y = 24-21\\y = 3

Thus, Katie can buy 3 large tubs of popcorn.

So:

x = 7-3\\x = 4

In addition, you can buy 4 small tubs of popcorn.

Answer:

3 large popcorn tubs.

4 small popcorn tubs.
