Place a lien company sells t-shirts at $5 and shirt shorts with six if total sales were 1,040. and people bought four times as many t-shirts and shorts what was the total number of t-shirts and shorts sold

Number of shorts = 40

Number of t-shirt = 160

Step-by-step explanation:

Let number of t-shirts = t

Let number of shorts = s

Price of each t-shirt = $5

Total price of t-shirts = 5t

Price of each shorts = $6

Total price of shorts = 6s

So,

5t+ 6s = 1,040Eq1

 Given:

Number of t-shirt = 4 (number of shorts)

So,   t = 4s Eq2

From Eq1 and Eq2

5t+ 6s = 1,040

5(4s) +6s = 1,040

20s + 6s = 1,040

26s = 1,040

Number of shorts = 40

Number of t-shirt = 4(number of shorts)

Number of t-shirt = 4(40)

Number of t-shirt = 160

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
